Rebel continued: "Everybody's asking me like, 'Why did you lose weight?' Well, clearly, it was to get the attention of Robert Pattinson, because you know what they say, once you got bat, you don't go back."

Rebel Wilson joked about her weight loss in her opening monologue at the BAFTAs
The actress couldn't resist throwing in one more joke before changing the subject. "No, guys, seriously I did not lose weight just for a guy, as if! I did it to get more acting roles… Boy, I'm now so excited I can play the non-funny love-interest in an Adam Sandler movie."
The star is hosting the awards for the first time in her career and was clearly thrilled by the gig. "How good is it that award shows are back in person?", she asked the audience to a rapturous applause.
Rebel Wilson looked incredible on the red carpet ahead of the event
