Dakota Fanning turns 19 years old today!

We've watched the actress grow up on the silver screen -- from one of her first starring roles in "I Am Sam" to her more recent parts in flicks like "The Secret Life of Bees" and the "Twilight" sagas.

It's hard to believe that the little blonde girl who played Sean Penn's daughter, Lucy, when she was just 8-years-old is almost in her 20s -- she'll even be making her first nude big screen debut  in "Very Good Girls" later this year!

But she's not the only Fanning who's been stealing the spotlight lately -- her sister Elle Fanning, 14, will play Princess Aurora in "Maleficent" alongside Angelina Jolie (in theaters next year!) and she's also starred in flicks like "The Curious Case of Benjamin Button" and "We Bought a Zoo."

Great acting chops definitely run in the Fanning family! So we gotta ask, who's the more talented sibling? Click "Launch Gallery" above to vote and see more famous related stars!
