It appears that Kristen Stewart has put on some weight recently, and it's supposedly making fans wonder if it's because she's pregnant- with Robert Pattinson's child.

Kristen Stewart & Robert Pattinson Spotted On Opposite Sides Of Country?

On Thursday, Hollywood Life reported that the actress has apparently gained about 10 to 15 pounds since filming her latest movie Still Alice, and a friend of the actress cleared things up with the site about a possible pregnancy.

It looks like any hopes of a future baby can be put on hold- at least for now.

Kristen Stewart & Her Ex Still Keep The Same Fashion Style?

"Kristen is absolutely not pregnant," the friend said. "She has put on a few extra pounds for a movie role and that's it. She's already so thin so a few more pounds makes a noticeable difference, she's still thin."

"Don't get me wrong, Kristen would love to be a mom one day and have little rugrats running around, but not for a while," the friend continued. Her priority right now is her work."

Lisa DeFazio, a celebrity nutritionist and registered dietician also made comments about Stewart's weight gain, saying that she actually looks healthier.

"In the before photos, Kristen [who is 5'5"] appears to be approximately 115 pounds, now she appears to weigh 125 to 130 pounds. You can see her stomach in her jeans now gives her a slight 'muffin top' around her waist and her thighs are a bit heavier," DeFazio said. "She definitely has gained weight, however, it is not a bad thing! She was getting to be too thin anyway, and now it appears she is eating, looks healthy, happy and has some curves."
