A report has suggested that Joe Jonas’ mum “isn’t thrilled” about his girlfriend Ashley Greene.

With the Jonas Brother and the Twilight actress travelling all over the country to spend more time with each other, things are looking serious between the pair.

However, Joe’s mum is said to be less than impressed with Ashley.

Joe’s family are really religious (his dad is a former ordained minister from an Assemblies of God church) and a friend of the family has told HollywoodLife.com that Denise isn’t Ashley’s biggest fan.

“Normally he’s the one calling the shots, but now Ashley’s the one leading the relationship,” the insider said. “She’s edgier and older than Joe’s other girlfriends and his mom isn’t thrilled about the situation.”

“They’ve instilled really moral believes in their boys, and Joe has always been the one to push the envelope a little bit. Denise knows her boys are heartthrobs, but she’s kind of nervous of the way Ashley has Joe wrapped around her finger.”

“She’s trying to give Ashley a shot,” the insider explained, adding, “But things are a little strained.”
