Justin Bieber is only 19, and, according to his mentor Usher, is still in the midst of growing up. But between the tattoos, the vandalism accusations and his recent arrest, Biebs is not the same "Baby" singer we met in 2009.
At 20, Miley Cyrus has been working in show business for more than a decade. The singer/actress has gone from being a fresh-faced preteen to a platinum blond vixen who scandalized the MTV VMAs in 2013 with her "twerking."
Selena Gomez's appearance hasn't changed dramatically since she starred on the Disney Channel's "Wizards of Waverly Place" in 2007, but her work sure has. Now 21, Gomez has stretched herself with more mature content, such as the risqué movie "Spring Breakers" and her suggestive new single, "Come and Get It."
Remember Derek Boyd, the ace "Yankee Doodle Dandy" singer on "Full House"? That was Blake McIver (formerly Blake McIver Ewing), whom you may also remember as Waldo from 1994's "The Little Rascals." These days, 28-year-old McIver is definitely more adult, as his Instagram account shows. The one-time child star told RumorFix that he's been working as a go-go boy in Los Angeles and is preparing to release his first album on Tuesday, November 5.
Alyssa Milano, who starred as a pre-teen on the '80s series "Who's The Boss?," thinks talent is one factor that helps a child star safely transition into more adult roles.
Seven years ago, Jaden Smith was a baby-faced child star appearing with his dad Will in 2006's "The Pursuit of Happyness." Although he's once again starring with his father in this summer's "After Earth," teenaged Jaden isn't a kid anymore.
Along with her older brother Jaden, 12-year-old Willow Smith has blossomed since she first appeared alongside dad Will in his 2007 film, "I Am Legend." The actress and singer showed a more mature look this spring at the May 2013 premiere of "After Earth."
Vanessa Hudgens came to fame as a Disney Channel star in 2006 but soon stepped away from her wholesome "High School Musical" roots. This year, the 24-year-old is appearing in more adult projects, such as "Spring Breakers" and "Machete Kills."
It's still hard to believe that Rudy Huxtable is now 34 years old. Keshia Knight Pulliam, the actress who played Rudy on "The Cosby Show" from 1984 to 1992, grew up on TV but acted sporadically since then. This year, she took a dive into reality TV with ABC's competitive diving show, "Splash."
Macaulay Culkin turned a scream and an exaggerated expression into a blockbuster movie franchise when he starred in 1990's "Home Alone" at the age of 10. He went on to co-star with in 1991's "My Girl," but has in later years not been a huge fan of being on camera. In April, he ripped into paparazzi in the UK for trying to take his photo.
Along with Knight Pulliam, Raven-Symone is one of the most recognizable child stars, thanks to her work on the long-running "Cosby Show" and her subsequent career on the Disney Channel. The actress has been in the business since the age of 3, and most recently appeared on ABC Family's "State of Georgia."
"Mad Men" fans have watched Kiernan Shipka grow up as Sally, the daughter of protagonist Don Draper. Having starred on the series since she was 7, Shipka's gone from being a little ballerina with a lisp to a teen girl with enviable poise over the series' six seasons.
One minute, Abigail Breslin was a 10-year-old "Little Miss Sunshine," and the next thing we know, she's flashing her bra in 2011's "New Year's Eve." The now 17-year-old is grownup enough to take on the older sister role, as she will in the November release, "Ender's Game."
Along with Vanessa Hudgens, Zac Efron was just a teen when he became famous with Disney's "High School Musical." Now 25, Efron caters to audiences well past high school, such as his turn in Lee Daniels' 2012 film, "The Paperboy."
Mary-Kate and Ashley Olsen have been in the entertainment industry since they were literally in diapers -- the pair took turns playing the youngest daughter of the Tanner clan, Michelle, on "Full House" from 1987 to 1995. They went on to star in their own movies, but these days the twins are better known for their fashion lines, Elizabeth and James and The Row.
Best known for his role as Renee Zellweger's cute-beyond-words son in 1996's "Jerry Maguire," Jonathan Lipnicki is now old enough to play Zellweger's love interest. According to IMDb, the 22-year-old has a dramatic film arriving this year starring Christopher Mintz-Plasse called "Tag."
Chloë Grace Moretz was a "Kick-Ass" actress even as a kid, starring in movies like "The Amityville Horror" at age 8. Now 16, Moretz has ditched the Shirley Temple curls but not her action moves -- the star will appear in the sequel to 2010's "Kick-Ass" this August.
Dakota Fanning has appeared in so many movies and TV shows since her career's launch around age 6 that we could put together her baby book. Now 19, Fanning is not only an acclaimed actress, but also a high school graduate.
Daniel Radcliffe's development has been watched by millions as he came of age in the "Harry Potter" movie franchise, which launched when he was 12. By 2007, Radcliffe was ready to show how grown-up he'd become and starred in "Equus" in London -- a stage production that required some nudity.
Along with her "Harry Potter" series co-star Radcliffe, Emma Watson's racking up proof that she's not little Hermione anymore. The 23-year-old actress plays a thief in this summer's "Bling Ring," and an ax-carrying marauder in Seth Rogen's comedy, "This Is The End."
Angus T. Jones wasn't yet 10 when "Two and a Half Men" first premiered on CBS in September 2003. A decade later, the now adult actor is ready to break away from the sitcom -- one that he's publicly said he finds distasteful -- and won't be a regular star on the 11th season this fall.
Amanda Bynes began working at 10, and by the time she was 14 had starring roles on two Nickelodeon shows. Yet around age 24, Bynes ceased her steady work schedule and claimed she was "retired." Lately, that "retirement" has translated into troubling run-ins with the law.
Lindsay Lohan showed acting prowess at 12 when she played a set of identical twins in the 1998 remake of "The Parent Trap." Lohan went on to star in movies like "Freaky Friday" (2003) and "Mean Girls" (2004), but her tumultuous private life soon interfered with her career.
Anna Chlumsky became a star at age 11 thanks to her role in 1991's "My Girl." After sporadic appearances on TV, the now 32-year-old, who's expecting her first child this year, has landed a hit comedy with HBO's "Veep."
- Justin Bieber was arrested in Miami, Florida, on January 23
- In the week and a half leading up to his arrest, he's been vacationing with friends
- On Instagram, he first shared photos of a snowy getaway
- His friend Khalil also posted photos of the two in Miami
(CNN) -- Five days ago, Justin Bieber wasn't worried about a thing.
And it wasn't because he didn't have a reason to be. The pop star has been under investigation for alleged involvement in a January 9 egg attack on a neighbor's home -- one that caused an estimated $20,000 in damages -- but you wouldn't know it from his tweets.
After police raided his Calabasas, California, home and seized his security footage and iPhone, Bieber was on Instagram sharing photos of a snowy vacation with friends.
His carefree attitude was emphasized in an Instagram post he captioned, "worried about nothing.'"
While the media has been running in circles over allegations ranging from drug abuse to public urination, Bieber's social life -- at least as depicted on his social media accounts -- never faltered.
Here's a breakdown of how Bieber's been spending his free time in the days leading up to his arrest:
Getting new ink
Biebs has gotten so many tattoos that they can make up their own guide. On January 12 he shared a photo of a freshly inked compass -- maybe he was feeling a little lost.
Snowboarding
For the past week, we've heard little from Bieber that didn't include him hanging out with friends. Word has it that the star has been thoroughly enjoying his break from concerts and work commitments.
Lounging (sometimes shirtless, because why not?)
Nothing says wealth like a near-empty chest of drawers and a selfie taken in slippers -- at least, that's how we're interpreting this Instagram post from five days ago. Or maybe he's trying to signal that his shorts were hanging a little low because of all the cash in his pockets? The prior shirtless snapshot is a little easier to figure out -- the kid is always thinking of his fans.
Pranking friends
No one knows whether it's Bieber's butt that's mooning a snoozing Lil Za -- one of Bieb's regular pals -- or someone else's, but he did feel comfortable sharing the bro prank with the world.
Smoking Cuban cigars and shooting hoops
We know that Bieber flew down to Miami on a Monday, and the reports of what he's being doing there -- aside from his recent arrest -- include spending $75,000 in a strip club. Bieber hasn't confirmed that bit of gossip, but we do know he's recently lit up at least one Cuban cigar and been to Lil Wayne's Miami-area skate park.
Tagging
Justin Bieber's love for graffiti art has only increased in recent years -- and sometimes it gets him into trouble. Yet it wasn't tagging his initials that got him popped by the cops in Miami ...
Cruising in a Lamborghini
We all know how this turned out. But before the police arrived, Bieber and his car companion -- who's been identified as model Chantel Jeffries -- were captured enjoying a night drive, an image shared on Bieber's friend Khalil's Instagram account.
All of which leads up to the early hours of January 23, when Bieber was arrested on charges of drunken driving, resisting arrest and driving without a valid license.
Obviously, given the circumstances, we can imagine that the star won't be sharing any Twitter updates for a while.
