Look at K-Stew -- being kind of fun!

Kristen Stewart appeared on Jimmy Fallon’s The Tonight Show -- and it almost looked like she had a good time!

On Monday night, Jimmy brought out an old photo of Johnny Carson and Eva Gabor playing Twister on the show decades earlier. To mark the 50th anniversary of the former host's game, the surly star and the late-night show host decided to play their own rousing game of Jell-O shot Twister.

The adult-version of the popular family game was pretty much the same as usual (place your arms and legs according to spins of the color wheel), only Jimmy's version had a Jell-O shot on each colored circle. The game is pretty quick -- so it really didn't take long for the funny man and the Twilight actress to feel the effects of the alcohol.

After a couple of spins, Kristen said, “I’m full, like really full." But the game went on! What a trooper!

The shots must not have rocked her balance too much -- the actress was able to beat Jimmy, who eventually collapsed under the pressure.
