Katy Perry and Diplo appeared to be "more than friends" at Coachella this weekend.
The 'Roar' hitmaker 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.
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 and Diplo were seen together again backstage on Sunday, 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.
