Blogger Bites Back: Robert Pattinson & Kristen Stewart caught kissing at premiere?

Twi-hards, we finally have evidence that Kristen Stewart and Robert Pattinson are officially on.

Reese Witherspoon might have given Pattinson's on-screen love game the big thumbs down, but his girlfriend and Twilight leading lady certainly has no complaints.

Pattinson premiered his latest film, Water for Elephants, co-starring newlywed Witherspoon, in New York City last night. And while Stewart was a no-show on the red carpet, sources say she did rock up at the premiere (she trotted in through a back exit) and the private after-party.

The couple was later spotted, along with Pattinson's parents, Witherspoon and her hubby Jim Toth at swanky eatery Le Cirque, which was decked out with brass elephants and circus balls, befitting the movie's theme.

"She looked amazing," a source tells Us Magazine, who spotted the "inseparable" pair sipping beer at their table.

The couple eventually left the bash together, hand in hand, at 1 a.m.

And then came the kiss...

The pair, who has never officially confirmed their romance, appeared to be indulging in a spot of PDA before the throng of paparazzi camped outside the venue.

There they were, sat in the back seat of a chauffeured car. R-Pattz cuddles up to his girl; he leans in, puckers up, and goes for it...

Awkward. I wonder what put her off...Garlic breath? Beer burp? Answers on a postcard, please.

More snappy evidence of the near lip-lock here.
