A witness told The Sun : “She brazenly sat there doing drugs in front of a roomful of people.
“She comes across as a bit of a goody two shoes, so I couldn’t believe it.”
After sniffing the powder from the table with the help of a banknote, she uses her finger to dab at what is left on the glass and licks her finger.
The source went on: “There were about 30 people there. Because it was in Chelsea, her stomping ground, she knew most of them.
“But there were people she didn’t know. I was shocked she’d do drugs in front of them.
“She’ll regret it if she is booted off the show.”
Olivia first appeared on Made in Chelsea earlier this year, but following the release of the video her days on the show could be numbered.
Mirror Celeb has reached out to Olivia’s representation for comment, and Channel 4 is yet to comment on her future in the show. More details here
