The "Part of Me" singer looked gorgeous in a decorated silk shirt, dark purple hair and reddish pink lips and was quite pleased to be with her Florence + the Machine lover boy.
Robert was right behind his leading lady and looked ready to get his party on! Katy had a bit too much fun at night's end, and flashed her cheeks as she got into the car for the ride home.
The reunited duo recently hit a snag in their relationship when they reportedly broke up last month, but have gotten back together in the past week.
Katy isn’t just a leading lady to her man, but also set to be one on the big screen!
She's being considered to play the Queen and girlfriend to Freddie Mercury in his upcoming biopic.
The movie, which also could star Sacha Baron Cohen as Freddie, should start filming next year.
Check out the partying couple in the accompanying gallery.
