Katy Perry Throws a Party For Rihanna, Leighton, and Mickey

Rihanna had dinner at Cipriani last night before joining celebrities like Leighton Meester and Sebastian Stan at Katy Perry's concert in NYC. Chris Brown was snapped passing by the restaurant, though her rep denied rumors of a reunion after the two after spent the weekend in the same hotel. At the show, Rih danced and sang along to the music as she sat next to Donald and Melania Trump. Katy hosted an afterparty at Club Griffin where the girls posed for pictures with lollipops and Mickey Rourke danced on a table with a blonde. It looks like everyone had a great time as the woman of the hour partied the night away with her famous friends and Barbados bikini buddy.
