Katy Perry and Diplo appeared to be "more than friends" at Coachella this weekend.
The 'Roar' hitmaker - who recently split from John Mayer after 18 months of dating - has been pals with the DJ for a long time, but onlookers at the first weekend of the Californian music festival said they looked closer than ever at the Jeremy Scott and Adidas Party on Saturday (Apr 12).
A source said: "Diplo was hanging out with Katy pretty much the whole night."
Another source added to RadarOnline.com: "They've been friends forever. It definitely looked like more than than that! At one point he even had his arms around her."
The 29-year-old singer reportedly had one female fan thrown out of the party - which she hadn't been invited to - after spending too long with Diplo, whose real name is Thomas Wesley Pentz.
The source added: "Katy had the girl thrown out! She was yelling and kind of upset about it. The girl didn't have a wristband and was a total sloppy party crasher, but still, it was kind of surprising."
Katy - who was previously married to Russell Brand - and Diplo were seen together again backstage on Sunday (Apr 13), and left together after watching Lana del Rey perform.
News of a possible new romance for the 'Dark Horse' singer could disappoint Robert Pattinson's friends, as it was previously reported the 'Twilight Saga' hunk's pals were hoping for a relationship between the pair after they were also seen hanging out at Coachella.
