Hold Up — Walt From Lost Got Hot

Walt, aka everyone's favorite sorta mystical tween from Lost, is all grown up! Malcolm David Kelley — who is now 21 — gave us a bit of a shock when he popped up at a special panel for Lost at PaleyFest in LA on Sunday to celebrate the show's 10th anniversary. We just thought that Walt would always stay Walt! Sadly, Harold Perrineau (aka, Michael) was not present at the reunion, but Malcolm's costars Ian Somerhalder, Maggie Grace, Jorge Garcia, Josh Holloway, Henry Ian Cusick, and Yunjin Kim were all at the Q&A, where they dished out secrets about the show, including what each of them stole from the set.
