Robert Pattinson's girlfriend Kristen Stewart might be pals with Katy Perry but it doesn't seem that Rob is after Katy, Justin Bieber and Selena Gomez left him out of their group last night.

The trio were hanging out at Chateau Marmont after Katy Perry's premiere of 'Part Of Me' last night, when they quickly made their getaway into a limousine bus.

Pair try and get into the party bus...

Their exit was guarded by big security guys, who refused to let paparazzi anywhere near the door... and Rob it seems.

Rob was with his pal 'Raising Hope' actress Shannon Woodward, who was left begging to get on to the bus.

Rob looks out of his depth in the back of the car...

Eventually security relented and the two managed to get access. But you can clearly see that Rob found the whole incident embarrassing, as he continued to nervous laugh throughout the whole incident.

Maybe if Rob lost his trucker cap they would've recognised him? Or maybe not.
