Mario Falcone has been filmed supposedly snorting cocaine in a friend's kitchen.
The footage, exclusively obtained by The Sun on Sunday newspaper, allegedly shows the 26-year-old star taking the drug after a night out and friends were reportedly shocked he didn't try to hide the fact he was sniffing the suspicious white powder.
A source told the newspaper: "We had been out as a group and wanted to carry the party on.
'The Only Way Is Essex' star Mario Falcone has been filmed supposedly snorting cocaine in a friends kitchen.
"Mario had his own ideas on how to do that, though.
"He just started snorting this stuff in front of everyone. No one could believe their eyes."
The video was filmed two months ago at a house in Essex and Mario is seen using a rolled-up bank note to snort the illegal drug.
The reality TV star's job on the ITV2 programme could now be hanging in the balance.
A source said: "This video could be the end of Mario's television career.
"He's become an important part of the show in the last three years but the show doesn't make exceptions for anyone when it comes to drugs. He should know that.
"The show is watched by millions and is in its 11th series now so producers are certainly in a position where they can drop characters who are more trouble than they're worth."
Possession of a Class A drug carries a sentence of up to seven years in prison, while supplying carries a maximum life sentence and an unlimited fine.
A friend of Mario's said last night: "He knows he's been a silly boy. He does regret his actions and is sorry.
"It's now up to show chiefs whether or not he gets suspended or gets the sack."
Meanwhile, TOWIE's James Lock also faces being axed from the show after being charged with possessing illegal drugs in April.
Mario's spokesman refused to comment on the video.
