Robert Pattinson And Kristen Stewart's Secret Romance Exposed?

Robert Pattinson and Kristen Stewart's passion isn't just reserved for the cameras, according to a new tabloid report that claims the pair like to cuddle up in their spare time too.

On Wednesday the net was flooded with pictures of a shirtless Rob locked in an enthusiastic embrace with on-screen lover Kristen as the couple filmed dramatic scenes for Twilight sequel New Moon in Italy this week.

And sources say that the kissing continues off set.

“I was on vacation in Vancouver when I saw Robert and Kristen holding hands as they left the bar Richard’s about 2 a.m. on May 5,” photography student Jessica Fettes tells the National Enquirer.

“They looked very happy together, and there was a lot of smiling. I saw them kissing after they got into a cab.

“From the length of time they kissed and the amount of touching they did, I am certain they are more than just friends.”

The co-stars have been persistently linked in the press, despite their denials and Kristen having a long-term boyfriend.
