For the second round, John Krasinski takes a different approach and surprises everyone with his emotional lip-syncing to Katy Perry's "Teenage Dream". He adds a personal touch to the performance by dedicating it to his wife, Emily Blunt, and the audience can't help but feel touched by his heartfelt rendition. Anna Kendrick follows up with an equally emotional performance of One Direction's "Steal My Girl", complete with an elaborate set and backup dancers.

The final round is a nail-biter as both stars bring their A-game to the stage. Anna Kendrick performs a show-stopping routine of "All I Do Is Win" by DJ Khaled featuring Ludacris, Rick Ross, T-Pain, and Snoop Dogg. She keeps the energy high with her dynamic moves and gets the crowd on their feet. John Krasinski delivers another unexpected performance with his rendition of "Proud Mary" by Tina Turner. He wears a wig and a dress and puts on a sassy and energetic routine that gets the audience laughing.

In the end, it's up to the audience to decide who the winner is, and it's a close call. Lip Sync Battle season 1 episode 4 is a fun and entertaining ride filled with surprising performances and memorable moments that will leave viewers wanting more.
