Emily Atack thought she was going to die after being offered ketamine in a night club bathroom.
The "I'm A Celebrity... Get Me Out of Here!" star has revealed she was once dragged into a toilet cubicle by another woman during a night out, and whilst she believed the woman was going to "kill" her, she was actually offering the 29-year-old actress "horse tranquillisers".
In a preview for her upcoming memoirs stage tour "Talk Thirty To Me", she said: "I'm with a group of Scousers and one of them pulls me aside as we're about to leave and goes, "Come on, b***h, we're going to the toilet".
"We're locked in this tiny little cubicle and all of a sudden she pulls out this thing from her bra. She pulls out this white powder.
"She goes, "Do you want some Ket?" Ketamine. I thought she was trying to kill me - she was just offering me horse tranquillisers."
The former "Inbetweeners" actress went on to insist she didn't accept the drug and has never tried it, and told fans she wasn't condoning the use of the substance.
During the performance at the Hawth Theatre in Crawley, West Sussex, Emily also spoke of her sex romp after this year's BRIT Awards, when she managed to lose her knickers.
She added: "I went home with a bloke - shock. I woke up, had no idea where I was. I s*****d him until about 10am. I left my knickers there. I'll be seeing them on eBay."
But Emily's stories might not be as dramatic as they seem, as her spokesperson said the tales are "exaggerated" for comic effect.
They said: "It's a comedy routine. The show is loosely based on Emily's life but the stories are greatly exaggerated and distorted for comic effect."
