Yet another report accusing Robert Pattinson of possessive behaviour when it comes to rumoured girlfriend Kristen Stewart.

Hollywoodlife.com reported that the two were spotted enjoying dinner with a close group of friends at SoHo House in West Hollywood, and that Rob only had eyes for Kristen. Aww.

A source told HollywoodLife.com: “He was very protective of her while out with friends. He had his arm around her constantly. He couldn’t take his eyes off of Kristen. It was a bit much at times, but that’s Rob.”

24-year-old Rob apparently seemed especially wary of interactions between 20-year-old Kristen and her On The Road co-star Tom Sturridge.

“Rob and Tom didn’t talk much all night. By looking at them, you wouldn’t have known that they are best friends,” the source said.

“But, Rob really had no interest in anyone at their table but Kristen. He wanted to show everyone including, pal, Tom Sturridge, that Kristen is his.”
