On Gossip Girl, Sage (Sofia Black-D’Elia) is Nate (Chace Crawford)’s 17-year-old girlfriend with a big chip on her shoulder. But we all know that most of time, television characters are a few years younger (or more) than the actors who play them.

Besides Gossip Girl and the soap, Sofia got the most face time as Tea Marvelli on MTV’s Skins, a teen drama based on the British show of the same name.

So, how old is Sofia Black-D’Elia? Wikipedia lists Sofia’s birthday as December 23, 1991, making her 20 years old.
