It's Walt From Lost!
Remember Walt? He was played by the now 20-year-old actor Malcolm David Kelley, who also appeared in the movies Antwone Fisher and You Got Served.
These days, Malcolm continues to act, and he also perform as part of the pop duo MKTO, and their video even features his dad from Lost, Michael Dawson.
He seems to have grown up so fast, it’s almost like he got caught in one of Lost’s crazy time-bending story lines!
