Marnie Simpson from Geordie Shore was pictured on Snapchat inhaling a balloon of nitrous oxide after Wireless Festival at the weekend.
The 24-year-old, who is engaged to *TOWIE'*s Ricky Rayment, was snapped clutching a yellow balloon, which had the caption "naughty" placed over the top.
She's now opened up about her regret, as she "wasn’t aware of the dangers" and has advised others to read up about the drug before trying it for themselves.

A spokesperson for Marnie told The Mirror: "Marnie wasn’t aware of the dangers of nitrous oxide, although she now is and deeply regrets using it on this one occasion.
"She advises anyone considering using laughing gas to read about the dangers on the Frank website."
Nitrous oxide is legal, however it can cause unconsciousness or even death due to the lack of oxygen users experience.
This risk increases if the gas is inhaled in an enclosed space or if a plastic bag is used that covers both the nose and mouth.
