Based mostly on a tracking of Britney’s mental health and a scientific round up of celebrity break ups.

2005.

2005 was a horrible year. Jude Law allegedly cheated on Sienna Miller with their kids' nanny; Nick Lachey and Jessica Simpson filed for divorce; Sophia Bush found out Chad Michael Murray had been sleeping with someone else; and Brad left Jen for Angelina. But worst of all, Nicole Ritchie and Paris Hilton fell out. On the plus side, YouTube was invented, which meant that we could all relive Tom Cruise's meltdown on Oprah.

2007.

A mixed bag of a year. On the one hand, the Spice Girls reformed; Skins started and swiftly became the best teen drama to have existed; and Wills and Kate temporarily broke up. But on the other hand, the last ever Harry Potter book came out; Britney shaved her head and Lindsay Lohan went into rehab three times and was arrested.

2002.

Romeo Beckham was born in 2002, making the world a more stylish place. But Justin and Britney broke up and Will Young robbed Gareth Gates of his rightful Pop Idol crown. Of course, 2002 was also the year that Gareth slept with Jordan and broke every teenage girl's heart.
