Uh-oh, Jennifer Hudson. Looks like you've got some competition. 

Broad City hero Abbi Jacobson is the latest celeb to take her turn on Lip Sync Battle, and in a sneak peek clip fans can see Jacobson fully committing to a powerhouse performance of the Dreamgirls ballad "And I'm Telling You I'm Not Going." (No surprise for anyone who watched Jacobson rock out to "Edge of Glory.)

Naturally, Jacobson's competition is her Broad City co-star Ilana Glazer -- but even Glazer seems impressed with Jacobson's performance. 

Glazer versus Jacobson's Lip Sync Battle airs Thursday, Aug. 6.
