Kristen Stewart showed off her lighter side when she took on Jimmy Fallon in a hilarious game called Jell-O Twister.
The often serious Twilight star appeared on America's Tonight Show and was challenged to go up against the host in a new version of Twister, in which they had to down shots of jell-o (jelly to those of us this side of the pond) every time they placed a body part on a coloured dot.
The first one to fall down was the loser.
At one stage it looked as if the wobbly stuff was going to get the better of Kristen, as she appeared to struggle to swallow it.
But the actress dug deep and powered through, eventually defeating a laughing Jimmy.
