Clark Gregg: beloved character actor and ... Britney Spears impersonator? Gregg (whom you may recognize as Phil Coulson from Agents of S.H.I.E.L.D., The Avengers, and other Marvel movies) takes on Hayley Atwell (Peggy Carter of Marvel's Agent Carter) on an upcoming episode of Lip Sync Battle, and based on the preview just released by Spike—it's going to be epic.
For a hilarious performance of Spears's "Toxic," Gregg, 54, dons a revealing blue flight attendant costume as he flounces down a mock airplane aisle delivering all the shimmies, shakes and thrusts from the original music video.
Watch the preview in the video above and tune in for the episode on Thursday, April 21, at 10 p.m. ET on Spike.
