In her new video, "I'm Grown," 15-year-old Tiffany Evans claims she's "on another level / I'm bringing things to life like I'm Geppetto." And we're inclined to agree with her. In addition to being rife with Pinocchio references, "I'm Grown" has it all -- the blindingly bright watermelon-themed outfits, the hot verse from the no-longer-lil Bow Wow, and the apparel-driven similes (e.g. "You're so stuck in the past / Like stone-washed jeans.") Was it really only two years ago that she won junior Star Search? They grow up so fast these days!
