It's just been a few months since the reported break-up of Katy Perry and John Mayer, but the 29-year-old Roar singer was recently spotted at the XS Nightclub in Las Vegas partying with 35 year-old EDM star (and rumored love interest,) Diplo (Thomas Pentz, in real life.)

People reported that Perry and an entourage of close friends partied in Las Vegas on a Monday night with Diplo spinning at the deejay booth. Perrys said to go incognito in a black handkerchief mask, sipping cocktails and dancing with her friends.

A source told People, "Even though she was on stage, most people didn't know she was there. She was twerking really hard and Diplo played Dark Horse."

The publication also added that earlier in the evening, Perry, who was wearing a blue and purple-colored cocktail dress sipped on Veuve Clicquot Yellow Label with Diplo and 14 others at Andrea's at Encore.

The International Business Times said that Perry was first linked to Diplo at the Coachella Valley Music & Arts Festival in California last April. It was also reported that they ended their fling a month later, but were reunited for a holiday in Jamaica last month.

In addition to this, the report also said that a source claimed that Perry and Diplo called off the relationship because it was moving too quickly and the EDM DJ wanted to introduce Perry to his family.

Meanwhile, in an interview with Rolling Stone magazine, (where the singer is the front cover for the August 14th issue,) Perry opened up about her plans to have children - with or without a man, Us Magazine reported.

"I don't need a dude! It's 2014! We are living in the future; we don't need anything. I don't think I'll have to, but we'll see. I'm not anti-men, I love men. But there is an option if someone doesn't present himself," Perry said.
