Megan Barton-Hanson had top lip sweats and was shaking on her "really awkward" 'Celeb Ex in the City' date.
The reality TV star anticipated one of three of her exes being her date on the MTV show, but she was "caught off guard" when someone completely different turned up, which left her "absolutely squirming" in her seat.
She exclusively told BANG Showbiz: "It was really awkward, I'm not going to lie. I was sweating on that date. It was bad.
"Everyone has watched 'Ex on the Beach' and knows an ex is going to come on.
"I was wishful thinking, thinking maybe it will be just two first dates and I've got to pick between one. No - it was an ex.
"I had pre-planned in my head that it would be one of three who I had been really public with, but it was none of those. It caught me off guard.
"It's going to be a different side to me that's going to be shown. I think I come across confident and powerful in the previous reality show I was on.
"But this one shows me absolutely squirming. I had top lip sweats, my chest in hives. I was like, 'Oh my God, this is not good.' "
The former 'Love Island' star was left "shaking" when the dreaded Tablet of Terror turned up, after she had tried but failed to get any clues from the production team about her mystery date.
She said: "When the Tablet of Terror turned up on the table I was shaking.
"I was trying to get answers out of the production team. Even leading up to me sitting down for my date I was like, 'Come on, give me a clue.' So I could pre-plan what my motive was going to be.
"But I had nothing. They were so tight-lipped."
Despite the awkward encounter, Megan admitted the show was "good fun".
She added: "But it was good fun and it's eye-opening. I do think you grow as a person when you put yourself in these positions.
"They're not necessarily comfortable, you're not necessarily going to love watching it back.
"I've seen the trailer and even my facial expressions say it all."
'Celeb Ex in the City' premieres tonight (08.12.20) at 9pm on MTV.
