Rob Pattinson and Kristen Stewart - seen kissing!!

Robert Pattinson and his "Twilight" costar Kristen Stewart were photographed entering a party in Canada on Sunday night and inside... things got hot and heavy! The two were seen kissing in the corner, foolishly thinking that some creepy fan wouldn't take their picture.

Don't believe me? Celebuzz has the photos!

So does anyone need ANY MORE confirmation that these two are doin' it? And here is the rest of it.
