Ryan Reynolds and Blake Lively kept tight-lipped when their baby daughter, James, was born last year. 

For AGES no one knew her name or even her birthday.

Well, as it turns out, James' birthday was yesterday, December 16, and Ryan posted a very amusing tweet to prove it. 

"Happy birthday to my baby girl! Sad I lost my virginity. But thankful I have a daughter."

Although the ridiculously good-looking couple were quite coy about their new bundle of joy, it didn't stop Ryan from talking about her non-stop during the year.

“I have no problem waking up five times in the middle of the night and changing diapers, and as exhausted as you get, I have this stupid grin on my face all the time,” Reynolds told GQ
