Aniston looked glamorous in an intricate, low-cut Roberto Cavalli dress with a simple silhouette, while Perry rocked a sleeveless black ensemble with a thigh-high slit. She paired the look with a layered pearl choker and a fun clutch with a Katy Perry Hollywood Walk of Fame star on it.

The gorgeous pair posed together at the premiere's after party, which is notable insomuch as both stars used to date musician John Mayer. Though their relationships with the singer were a few years apart, it's nice to see that their shared ex doesn't come between them. No "Bad Blood" here!

Olivia Munn also looked stunning, donning an all-white, mish-mash dress with cutouts, fringe and spaghetti straps.
