Kristen Stewart has revealed that her own grandparents believed the rumors she was pregnant.

The Twilight actress and rumoured girlfriend of co-star Robert Pattinson ignores all the weird and wonderful stories written about her in the press, but admits that some of her family still wonder what is true and what is made up.

“I had my grandparents call my mom when people thought I was pregnant for a while,” says Kristen.

“I don’t really know why but my grandparents believed it. They were convinced. My mom was like ‘You guys, you have to stop reading all this stuff, because that’s not the case. You should stop reading magazines in the grocery store’.”

Kristen recently spoke about dieting for Breaking Dawn.

“I want a cheeseburger so badly, but, you know, I have to be a vampire in a few weeks,” Kristen told the LA Times‘ Amy Kaufman at lunch in Los Angeles, before opting for a veggie burger instead.

Her character Bella will be spending a lot of time pregnant with her first child in the upcoming flick, which means Kristen has to wear and uncomfortable fake bump.

“I’ve worn it. It’s … crazy. I’ve done fittings,” she said. “It gets immense. It gets so massive at some point that it actually looks inhuman. Like it’s hurting her. There are striations of bruises.”
