On Bravo’s Watch What Happens Live on Tuesday, host Andy Cohen put actress Emma Roberts, niece of Julia Roberts, on the spot in the Plead the Fifth segment by asking her who’s the biggest diva— her Scream Queens costar and New Jersey native Lea Michele, or singer Ariana Grande.

Emma wisely eluded the question but dished up plenty of other juicy opinions, which you can watch her share on Bravo’s website.

On #ScreamQueens she's shrewish and @BravoAndy loves that he's Jewish. It's #WWHL with @EmmaRoberts and #DaveFranco! #NERVE

What else happened on the episode?

Emma and Nerve costar Dave Franco were on to discuss the film, though of course it’s WWHL so they had plenty of other fun, including reenacting a scene from one of Emma’s favorite scenes in Vanderpump Rules. Emma played reality TV star Stassi Schroeder, while Dave played Kristen Doute.

Emma earned the highest of praise from Stassi, who Tweeted, “Emma does me better than I do me,” while Kristen had a slightly different take on the stars’ impressions.
