Joe Jonas might be burnin' up when he hears the latest rumors about his relationship.

The 23-year-old hottie has been dating 28-year-old aspiring model Blanda Eggenschwiler for almost six months, but sources say she is using him for fame, according to Radar Online.

“Blanda can’t get enough of the attention she’s receiving now that that’s dating Joe, and she actually believes she’s famous now,” a source reveals.

As it turns out, Blanda doesn't even enjoy Joe's music.

“She told me, ‘I don’t even like their band. I just go to their show, appearances and meet-and-greets so the fans will talk more about me and buy my products,'" continues the source. "She’s all about herself lately and expects Joe to shower her with public attention."

Apparently, Blanda is a big fan of getting her photo taken by the tabloids.

“She walks around acting as if she owns everywhere that she steps," adds the insider. "She wouldn’t even hang out with her friends much at Coachella because she was worried she would miss a paparazzi opportunity."

What's worse is that she apparently limits the time he can spend with his mom.

“Blanda has a lot of control over Joe and his actions,” says the source. “She continues to brag about how she has so much control over him and she tells him when he can and cannot see his mom. To her, everything should be about her.”

Yikes. We find this a bit hard to believe, since we think Joe would have picked up on any negative vibes from Blanda after dating her for six months now. Perhaps this "source" just has an issue with Blanda for some reason?

Let's hope Joe finds happiness, no matter who he's with.
