Joe Jonas' girlfriend is reportedly just with him for the fame, according to one close friend.
The sources said Blanda Eggenschwiler doesn't even like the band or the music and just goes to their shows so fans will talk about her.
"She's all about herself lately and expects Joe to shower her with public attention," the source said.
"She walks around acting as if she owns everywhere that she steps. She wouldn't even hang out with her friends much at Coachella because she was worried she would miss a paparazzi opportunity."
She also is supposedly losing focus on her career.
"She's never in New York anymore working on her career. Her life is pretty much dedicated to paparazzi shots, and her addiction to the attention she gets from his 12-year-old fans," the source said.
And Eggenschwiler has Joe whipped, too.
"Blanda has a lot of control over Joe and his actions. 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."
