Last night, viewers saw Charlotte's hilarious EOTB arrival as the 24-year-old emerged from the sea in full on scuba gear.
Suprising former flame Gaz, Char has now joined him in the villa and not phased by his current romance with Anita Kaushik, she admits: "The whole time I've known Gary I've had to see him with other girls."
Used to seeing her on/off beau turning his charm on for other girls in front of her, Charlotte said in a new clip released by MTV: "Me and Gary have never actually been in a serious relationship... I'm not quite sure how to feel about it, but I don't think I'm not going to be heartbroken over it."
Although, she did admit she will find it "weird" being around Gaz when he is dating Anita.
She joked: "Normally he just sh*gs them and tells them to f*** off!"
Gaz, meanwhile, revealed he knew Charlotte would be his ex to emerge out of the sea.
"The main person I've been involved with for the last four or five years is Charlotte," he said. "Out of all my exes, surely it had to be Charlotte."
He added: "We live together for six weeks [on Geordie Shore], then we go off and do our own thing for 2 or 3 months, and then we live together again. Everytime we're living together [feelings] come back."
Geordie Shore fans last saw Gary and Charlotte rekindling their romance in the last series of the show.
Despite now dating Mitch Jenkins again, Char initially split with her boyfriend last summer and found herself getting close to Gary.
On the show, the pair went for their very first date, and Gary even admitted he was actually enjoying being Charlotte's 'new boyfriend'. But, any hopes of 'Chaz' reuniting for good were dashed when Charlotte decided to call things off between herself and her co-star, suggesting the pair were better off as friends instead.
Ahead of their debut on Ex On The Beach, Charlotte and Gaz told Reveal there was NO romance between them while staying in the villa.
While Gary said the pair's friendship reached "new levels" during their time on EOTB, Charlotte told us she and the self-confessed ladies man were not as close as they usually are.
"We were in different frames of mind [during EOTB], it was just different," she said.
We wonder who did catch Charlotte's eye then...
Ex On The Beach continues next Tuesday 3 March at 10pm on MTV.
