Who knew that Bridget Jones was so adept at sumo wrestling while dressed as a robot?

Renée Zellweger stopped by 'The Tonight Show with Jimmy Fallon' last night as she pushes on with her press tour for 'Bridget Jones's Baby' and that wasn't the only thing she was pushing as her and Fallon engaged in a game of 'Heavyweight Wrestling' with the host dressed as Santa and Zellweger dressed as some sort of rotund neon robot from the future where everything is obese.

You'd think that Fallon would have a height and weight advantage, but you'd be wrong because Zellweger has some fancy footwork and a fighting spirit.

Zellweger also took time on the show to show Fallon her Seventh Grade cheerleading routine which, as much as she tried, he couldn't really get the handle of. But major props to her for still being able to high kick like a 12-year-old at the age of 47.
