Who Is the Bigger Diva: Ariana Grande or Lea Michele?

For years, Ariana Grande and Lea Michele have been rumored to display some diva-like behavior in Hollywood. So when they filmed the first season of Scream Queens together, you may have wondered if the biggest diva-off ever occurred on set.

But who is the biggest diva of them all? Andy Cohen just had to know when Ariana and Lea's Scream Queens co-star Emma Roberts stopped by Watch What Happens Live Tuesday night and participated in a round of Plead the Fifth.

Unfortunately, Emma pled the fifth to Andy's question about whether Ariana or Lea is the bigger diva, which either means nothing or it means everything. Let the diva-off continue! 

Andy kept the juicy questions coming as he went on to ask Emma to name her least favorite movie starring her aunt Julia Roberts. "Well, I haven't seen the last couple that have come out," she told Andy before agreeing with his suggestion that it's "probably Mother's Day."

Emma also had to make some tough decisions among her hunky former co-stars during a round of Marry, Shag, Kill. "I'll marry Liam Hemsworth, I'll shag Nick Jonas, and I'll kill Dave Franco," she said, with her Nerve co-star Dave sitting right next to her. 

And just to confirm the awkwardness of the situation, all Dave could sarcastically say to that was, "I feel like I'm doing well on this show." 

Emma had even more Scream Queens tea to spill during her visit to the Bravo Clubhouse. Watch her dish on next season's guest stars, below.
