2. Joseph Gordon-Levitt
Like Leo, Joseph, now 29, got his start as a child actor. Early credits include Angels In the Outfield and the TV series Third Rock From the Sun. After taking some time off to attend Columbia University, the LA-native made a resurgence with a string of indie flicks including Manic and the surprise hit 500 Days of Summer.
Though his 500 Days’ character wasn’t so lucky in love, The GI Joe star is doing all right and has been linked to beauties including Julia Stiles, Evan Rachel Wood, and most recently, model Devon Aoki.
