Ali Larter may be best known for her role on the hit TV show Heroes, but one of Andy Cohen's favorite career highlights is her part playing opposite Beyoncé in the cult movie Obsessed.

Andy also rolled a hilarious remix clip of their brawl, where their best punches and throws are given an ultra-dramatic treatment. What's Beyonce look like when she's pulling hair and throwing shade? Watch the clip below.
