People.com Celebrity Katy Perry Parties with Rumored Boyfriend Diplo in Las Vegas The pop star and DJ haven't publicly addressed their relationship By Michele Corriston Published on September 28, 2014 03:00 PM Share Tweet Pin Email Katy Perry really is “Waking Up in Vegas.” The pop star continues to fuel speculation that she’s romancing DJ Diplo, partying as he performed in Sin City after selling out her own show at the MGM Grand Hotel’s Garden Arena on Friday night. Perry, 29, held court in the VIP section during Diplo’s set at Surrender Nightclub in Encore at Wynn Las Vegas, a source tells PEOPLE. The singer sipped water and bopped her head along to her rumored beau‘s music as her pals drank Grey Goose and Moet Ice, ordering pizza to their table later in the night. She left the club as his set drew to a close, and Diplo exited shortly after at about 3:15 a.m. This isn’t the first time the two partied together in Vegas: Diplo also spun tunes as they celebrated a friend’s birthday at XS nightclub in July. What Katy Perry Learned About Herself in Therapy And in August, Perry told Rolling Stone that she prefers to date musicians. “What I really like is someone that understands music, because I love music,” she said. “So anybody that understands the power of music, I’m usually instantly attracted to.” • Reporting by MELODY CHIU Want more stories like this?
