Watch Robert Pattinson Make Kristen Stewart Cringe With "Now You're Pregnant" Remark

Robert Pattinson graced the stage multiple times during last night's MTV Movie Awards and seemed to say whatever popped into his brain. Just ask Kristen Stewart, who found herself shrinking in her chair when the British actor accepted the award for Best Fight Scene with fellow Eclipse castmates Bryce Dallas Howard and Xavier Samuel.

Rob had trouble filtering his thoughts during last night's ceremony.

When the Eclipse trio accepted the popcorn for Best Fight Scene, Rob boasted, "Yeah, I won" of the epic battle between Edward, Riley (Xavier) and Victoria (Bryce).

"I guess I should say I'm so sorry I tried to hurt you Rob," Bryce quipped.

His response: "It's fine. I ripped your head off, and now you're pregnant."

After the bizarre comment, MTV cameras cut to Kristen who was seen mouthing, "What the.." as she shook her head and ducked in embarrassment.

Bryce is pregnant with her second child and showed off her baby bump last night; however, Rob's joke didn't seem to make sense to anyone, including his costars.

"That was a really advanced joke," Bryce told MTV. "I didn't get it."

"I'm not sure what..." Xavier said. "I guess in Breaking Dawn Bella's pregnant, so I guess that's the joke?"
