ROBERT Pattinson is caught up in a drugs scandal.

The British actor has been seen happily posing near what appears to be a bag of mysterious white powder, reports RadarOnline.

In a photo that was published on Facebook on November 17, a bleary-eyed Pattinson is seen partying  at an L.A. bash with pal Katy Perry‘s BFF Mario Fanizzi..

In the background, unbeknownst to both, another individual is caught red-handed, passing a friend a small plastic baggie filled with unidentified white powder.

Back in October, it was claimed that Rob went on a massive cocaine bender.

A source claimed Rob was “snorting bump after bump of cocaine” while in the VIP area of the Viper Room club on September 7, part of an alleged “wild cocaine binge that spanned three different locations and lasted nearly until dawn.”

“Rob was doing coke all night… Rob tried to be subtle by scooping the coke out of a baggie with a key, but he was still in plain view of others in the room — and he looked like he knew exactly what to do,” said the mole.

The source says Pattinson “continued to party excessively” at the Chateau Marmont.

“Rob went to the bathroom alone multiple times with the bag of cocaine,” notes the alleged insider.

“He got nervous, anxious and defensive toward the end of the night, which seemed in keeping with all the coke he’d been doing. He was paranoid that people were watching him.”

The party then moved to Pattinson’s house, reports Star.

“Once we got there, Rob quickly suggested that the guy with the coke break out the drug again. He was craving more and wanted the party to continue,” said the mole.

“He needs to stop hanging out with certain people who are not concerned for his well being.”
