An actor, director and writer, Marvel's Agents of S.H.I.E.L.D. star Clark Gregg was already a triple threat, but now he can add "fierce lip sync artist" to that already-impressive resume.

Spike TV has debuted a sneak peek at Gregg's showdown with Marvel's Agent Carter star Hayley Atwell from this week's Lip Sync Battle, and is it ever a doozy. Donning a futuristic flight attendants' uniform like the one Britney Spears wore in the music video, and flanked by backup dancers, Gregg gives "Toxic" his all ... and then some.

Check out the preview below, and watch the full episode Thursday at 10 p.m. ET/PT on Spike TV.
