Robert Pattinson and Kristen Stewart spotted sharing a back-seat smooch

London: Reese Witherspoon might have given Robert Pattinson’s on-screen love a big thumbs down, but his girlfriend and Twilight leading lady Kristen Stewart certainly has no complaints.

Stewart, 21, was spotted kissing her Twilight co-star, 24, in the back seat of a car as they left an after party following the New York premiere of his new movie ‘Water For Elephants’, reports the Daily Mail.

The actress was carrying her high heels in her hands and looked giddy as she leaned in for the affectionate moment.

The brunette, who is always eager to keep her relationship out of the spotlight, had skipped the red carpet but turned out to support her boyfriend at the private bash.

Pattinson instead attended the screening with his co-star Witherspoon, who had just days earlier described the pair’s love scenes as ``unpleasant``.

Pattinson has been dating Stewart since 2009 and the pair has recently been filming ‘The Twilight Saga: Breaking Dawn’, both parts 1 and 2, which is expected to finish later this month.
