Clark Gregg is 'Toxic' competition on 'Lip Sync Battle'

Clark Gregg threatens to take us to a magical place with his rendition of Britney Spears' classic Toxic. Thankfully, he was only clad in a skin-tight stewardess uniform and not the iconic sheer bodysuit.

The Agents of S.H.I.E.L.D. star goes up against fellow Marvel super agent Hayley Atwell, from Agent Carter, who was probably thinking about how she could pull off that stewardess costume much better.

The two Marvel TV stars' appearance on Lip Sync Battle is a culmination of their shows' online "Dubsmash War" which started off as a joke in which the cast members lip synced to random songs through an app called Dubsmash, and morphed into a charity-raising campaign.

As you can see from those early Dubsmash videos, Gregg is no stranger to dressing up in more ... form-fitting outfits.
