Lip Sync Battle is about to get a heavy dose of realness, thanks to Abbi Jacobson. In the preview clip above, Abbi gives an impassioned rendition of "And I Am Telling You I'm Not Going," the showstopper from the musical Dreamgirls. The Broad City [1] star is going against her partner in crime, Ilana Glazer, and only one comedy queen can come out on top. Given the fact that Broad City is jam-packed with tons of hilarious one-liners [2] and a veritable gold mine of feminist moments [3], this is one head-to-head battle you really won't want to miss.
