The reality show favourite hit the headlines over the weekend when The Sun claimed to have footage of him snorting a white powder on a night out.
A spokesperson for TOWIE has confirmed to Reveal that Mario, 26, will not join his co-stars in Marbella for filming on the new series while the allegation is being investigated.
Mario has been accused of snorting the powder off a kitchen table in Essex while surrounded by a group of pals.
It's claimed the alleged incident was shot two months ago.
Mario has yet to comment.
A source told The Sun on Sunday: "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 rest of the TOWIE cast are currently in Marbella filming the opening episode for the upcoming twelfth series of the ITV2 show.
