Gregg Sulkin will hit the “Lip Sync Battle” stage on Thursday to perform Kelis’ 2003 hit “Milkshake” while donning a wig — but not a shirt.
His shirt torn off in the first few seconds of the clip, the actor gives his competitor Victoria Justice a lap dance and busts out moves while whipping out an actual milkshake as a prop.
The audience drinks up the shirtless “Pretty Little Liars” star, who will battle Justice on Thursday night’s episode of the show. It looks like both MTV actors are throwing it way back to the early 2000s — Justice will perform Nelly’s 2002 hit “Hot in Herre.”
