Robert Pattinson sunglasses Water For Elephants blue jeans sneakers twilight

Rob Pattinson appeared on Jimmy Kimmel Live last night to promote his new flick Water For Elephants, and the handsome actor flashed hundreds of eager Twilovers a sexy grin as he entered the studio.

Rob chatted about everything from working with Reese Witherspoon to his love of cartoons, and when the actor wrapped up the interview, he spent plenty of time posing for pictures and signing autographs.

Water For Elephants opens tomorrow -- will you catch Rob and Reese on the big screen?
