Robert Pattinson and Kristen Stewart kissing on premiere night (VIDEO) and pics

Kristen Stewart made a low-key appearance at the party for Robert Pattinson's Water For Elephants premiere in NYC last night, but there was nothing discreet about the hot kiss they shared when they hopped into their car afterward — She was spotted leaving the bash with Robert, holding onto his arm and wearing a hot dress that was reportedly designed by J.
