Robert Pattinson and Kristen Stewart aren't known to show much affection in public.

But on Sunday, after Stewart, 21, joined Pattinson's parents at his Water for Elephants premiere in New York, the Twilight duo was caught getting cozy.

Stewart didn't join her British beau, 24, on the red carpet where he posed with costar Reese Witherspoon. But she certainly seemed to show her support after the party, as the two shared a smooch – and a smile – in a car before speeding off.
