The cute couple arrived just before 10 p.m. The "Teenage Dream" singer hit the red carpet solo in a cleavage-baring blue gown and posed for photos while her man skipped press by walking in behind the carpet. While entering the bash, Perry stopped to sign autographs for excited fans before walking in.
Mayer, who was carrying a camera over his shoulder, helped Perry pic up her dress as they made their way to their table inside. Perry sat down and sipped a drink while chatting to pals. The lovebirds chatted with Kacey Musgraves and Mayer took pics of Perry and Musgraves with his camera during their convo.
