Katy Perry continues to fuel speculation that she's romancing DJ Diplo as the pop star was spotted partying in Las Vegas.
Diplo performed in Sin City after Perry sold out her own show at the MGM Grand Hotel's Garden Arena last week, reported People magazine.
The 29-year-old singer sipped water and bopped her head along to her rumoured boyfriend's music as her close friends 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 is not 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.
