Glenn Close proved to be a real big mouth during a recent TV appearance - after she was challenged to see how many baby carrots she could fit into her mouth.

The veteran actress showed off a photograph of her daughter Annie with a mouthful of carrots while she was being interviewed by Jimmy Fallon during his Late Night show on U.S. TV on Tuesday.

Close explained to the host the picture was taken after her family decided to hold an impromptu competition at the dinner table.

She said: "There's always a contest going on (at our house). We were having dinner and there's a lot of carrots around and we said, 'Let's just see who can fit the most carrots into their mouth.' And Annie won - she fit 42 carrots."

Fallon then stunned the Fatal Attraction star by revealing a giant bowl of carrots from under his desk - and challenging her to another round of carrot fun.

But their TV showdown wasn't even a close call - Fallon erupted into fits of giggles as a victorious Close expertly tucked the veggies beneath her tongue.
