The mother of Diplo appears to have poured cold water on speculation that he is dating Katy Perry.

The 'Roar' star is a single lady after splitting from boyfriend John Mayer recently and she has been spotted with the US DJ, whose real name is Thomas Wesley Pentz.

His mum Barbara Pentz, however, told RadarOnline that Diplo revealed to his dad that the duo are just friends at the moment.

She said: "He hasn't discussed it with me, but he did with his dad. He said 'we're just hanging out. We're just friends right now'. I don't think it's a big deal right now. I don't think they'll be wedding bells yet. They're both doing their own things right now and on opposite coasts. He doesn't seem to be making a big deal about it."

However, Pentz is keen to get in and about the action if the relationship does indeed take off. She added:

"He hasn't mentioned bringing her home to mama just yet. But I think he would before it gets serious. Of course, she's got to be grilled by the mom.

"I wondered if it was a publicity stunt. It did occur to me. They both do like the cameras. [But] she seems like a lovely girl."
