Ryan Reynolds Reveals Baby Daughter’s Birthday On Social Media

Ryan Reynolds has revealed an important detail about his and wife Blake Lively's baby daughter – her birthday!

On Wednesday, the "Deadpool" star celebrated little James turning 1 with a Tweet that finally confirmed exactly when she was born.

"Happy birthday to my baby girl!" Ryan wrote, before including his signature humor in the brief tribute. 

"Sad I lost my virginity. But thankful I have a daughter," he added. 

Ryan and Blake were reported to have welcomed their first child together in late 2014, but had not made her specific birthdate public until now. 

The couple also held off on announcing her name until she was three months old, a decision Ryan said at the time was in her – and maybe his – best interest.

"I didn't want to be the first guy screaming it out to the media," he told the "Today" show. "Because as we know, little girls turn into teenage girls and little teenage girls sometimes scan through the archives and go, 'Why did you do that?'"

While James' face has yet to make an official debut, Ryan couldn't resist giving fans a peek at her tiny hand in a sweet Instagram post in May. 

Thumb wrestling isn't always fair. Curiously, my hand is the small one.
