Made in Chelsea's Spencer Matthews could be axed from the show after allegedly being caught using cocaine.
The 23-year-old PR man was apparently photographed taking the drug at a party at a club-goers house after a nightclub appearance.
E4 star Spencer even brought up the incriminating images in an attempt to conceal his bad behavior, according to The Sun.
One fan who was with the group in Bath, Somerset, said: "He produced a bag of cocaine, grabbed a DVD case and did a line.
"It made me feel really uncomfortable - but he acted like it was the most natural thing in the world."
The wealthy reality TV star could see his career suffer and could lose out on further work if he is found to have been using illegal substances.
A source said: "Spencer was about to sign a big deal but this could put a spanner in the works."
It's not the first time the star has faced criticism for being unprofessional. The newspaper reports that he has been pulled up by bosses of the series in the past after turning up to film scenes while intoxicated.
