Clark Gregg Channels Britney Spears in ‘Lip Sync Battle’ Preview (VIDEO)

This Thursday (April 21), Clark Gregg will be joining his dubsmash rival Hayley Atwell to compete on Spike TV’s Lip Sync Battle.

And based on Gregg’s Britney Spears impersonation while lip-syncing “Toxic,” he has a pretty good shot at winning the coveted LSB Championship Belt.

Of course, knowing Hayley Atwell, she probably has an ace up her sleeve, but is that ace enough to take down some cross-dressing and back up dancers?

Find out by tuning into the full episode Thursday, April 21 at 10 PM EST, 9PM CT.

For now, you can watch Gregg tasting poison paradise while dressed as a flight attendant above!
