It's on: the "Agent Carter" and "Agents of S.H.I.E.L.D." dubsmash war has officially begun with a video from Team Carter, which features "The Muppets'" Miss Piggy and Beyonce's "Single Ladies." You can check out the video and vote for Team Carter on the competition's CrowdRise page.

Last month, the casts of "Agent Carter" and "Agents of S.H.I.E.L.D." announced an interactive dubsmash competition with a raffle contest that will send one winner to Hollywood for dinner with Hayley Atwell, James D'Arcy, Clark Gregg and Chloe Bennet.

In the contest, the "Agent Carter" cast will go head-to-head with the "Agents of S.H.I.E.L.D." cast for a second time using dubsmash, an app that allows users to record a brief lip sync video to the song of their choice. This new "Dubsmash Death Match" will go three rounds, and fans will be able to vote for their favorite videos for $1 a vote. Whichever team gets the most votes wins, and the losing team will donate an additional $2,000 to a charity of the winner's choice and perform a dupsmash chosen, choreographed and costumed by the winning team. Team Carter represents Stomp Out Bullying, while Team S.H.I.E.L.D. has selected St. Jude's Children's Research Hospital.

Each vote will enter fans into a random drawing contest. The winner of this random drawing will receive a trip out to Hollywood, California for dinner with Atwell, D'Arcy, Gregg and Bennet and get the opportunity to appear in a dubsmash video with the stars.
