Olivia Bentley has been suspended from E4's Made In Chelsea over a 'shock video' published by a Sunday newspaper.
The Sun on Sunday released video allegedly showing Olivia taking drugs at the weekend.
Olivia, who joined the E4 series earlier this year, was captured on camera at a recent party supposedly taking a white powder.
"There were about 30 people there. Because it was in Chelsea, her stomping ground, she knew most of them," a source told the tabloid. “But there were people she didn’t know."
Sources say that Olivia faces a showdown with bosses over her future on the show following the video's release.
"She’ll regret it if she is booted off the show," the source added.
A spokesperson for the E4 series said yesterday: “Olivia has been suspended from the show pending an investigation.”
It's the second recent controversy to hit Olivia after the family of Bentley Motors denied she was related to the car maker's founder.
W.O. Bentley's step-grandson Miles Hutton told the Daily Mail newspaper that claims Olivia was the great-great-great-granddaughter of Mr Bentley were false.
He said: "She was probably hoping nobody would take any notice. But W.O. Bentley was Grandpa to us, and we are very proud of what he achieved. We don’t like to see his name taken in vain."
A spokesperson for the show told the newspaper that Olivia was a "distant relative of the Bentley family" but didn't "have the precise details" on her relation.
Made In Chelsea continues Monday night on E4.
