. . . or has Joe Mazzello grown into quite the hottie?!
The 26-year-old former child star -- you may recognize him from Jurassic Park or Simon Birch -- is looking pretty fine in Details Magazine (left).
But Mazzello isn't just a pretty face. He'll next be seen in HBO's 10-part World War II epic the Pacific, executive produced by Steven Spielberg.
He's currently working on the Social Network, in which he stars as Facebook cofounder Dustin Moskovitz.
