Gwyneth Paltrow is way into cooking and a total foodie!
So of course she had a great time while on chef Jamie Oliver's new TV show Jamie and Jimmy's Food Fight Club.
She and Jamie's co-host Jimmy Doherty faced off in a food challenge… the chubby bunny challenge!
If you're unfamiliar with the challenge, what you do is put a marshmallow in your mouth then say "chubby bunny."
You repeat this until you run out of mouth space or choke to death.
Luckily, neither contestant died… but who was the winner??
Check out the video (above) to find out!
