23. No, it's not the number of boyfriends Taylor Swift has had this year.
It's her age, as the musical superstar celebrates a birthday today!!!
Swift has made constant headlines throughout 2012 (where will she rank in our Celebrity of the Year countdown?!), largely for her music... but also for her personal life.
As of this writing, Swift is definitely dating Harry Styles of One Direction, while her latest album has already gone Triple Platinum. It's been a very, very impressive few months, even by Taylor's high standards.
So sit back, enjoy the following montage of Taylor Swift photos, and send in your birthday wishes to the icon now!
