Olivia Bentley, made famous by Made In Chelsea, has been suspended from the show after video emerged of her appearing to snort a white substance.
The footage, obtained by the Sun on Sunday, appeared to show her sitting at a coffee table snorting a powder before putting it on her fingers and licking them.
In the video she can be heard saying: "I'm on a TV show, so people write s**t all the time."
The photographer, who specialises in nude photos, first appeared on the reality show earlier in the year when she took photos of the other cast members.
A spokeswoman for Made In Chelsea said: "Olivia has been suspended from the show pending an investigation."
