The 24-year-old told how, while shooting for the reality show, she fell from a boat and was almost pulled under by the current.
Sympathising with Kym Marsh, who recently revealed her own scare following a worrying plane journey, Charlotte recalled the scary incident.
Writing in her column for Star, Charlotte said: “When we were filming for Geordie Shore, I got stuck underneath a boat.
“I fell out and was dragged along by the boat with the current. I thought I was a goner.”
Thankfully Charlotte was unharmed, and she added: “I got stuck on a rock so I could come up for air.”
Meanwhile Charlotte’s former co-star Vicky Pattison recently dismissed rumours of a feud between them.
Speaking to Now! magazine, Vicky said: “It couldn’t be further from the truth . I still speak to Holly [Hagan] and Charlotte.
“There’s absolutely no rivalry and nothing malicious there at all. I’ll text Charlotte and say, ‘Oh, you’re looking great at the minute, mate. Well done you skinny bitch!’”
“There’s certainly nothing unhealthy or nasty.”
