Marnie Simpson feels "physically sick" when she thinks about her failed fling with Gary 'Gaz' Beadle.

The 'Geordie Shore' star - who has had her fair share of doomed romances over the past three years - briefly dated her womanising co-star two years ago but she has admitted she deeply regrets their tryst and wishes she could erase the whole sexual ordeal from her memory.

She explained: "If I'm honest, I feel physically sick with what happened with Gary. If I could go back in time that would be the one thing I would change. It makes me sick up when I think about it."

And the brunette beauty - who last week announced she is bisexual - believes her co-star Charlotte Crosby will feel a lot better about herself if she took on the same mentality.

She said: "I'm not a fan of Gary... 100 per cent Gary has affected her confidence and I don't know why Charlotte got that involved with him. I feel like she put up a massive wall.

"She was confident and she was doing her own thing and I don't feel like she was that into him and he just sucked her back in. He's definitely manipulative."

The 24-year-old reality TV star thinks the blonde beauty - who has been in an on/off relationship with Gaz for five years - should cut ties with the 27-year-old hunk once and for all otherwise they'll just keep going round in circles.

Speaking to Mail Online, she said: "Their love story goes round in circles but I will say I think Charlotte can do a million times better than Gary and I just think on every level she's just far too good for him.

"I've always said that but I was always a fan and I did want them to work out but I just don't think it's meant to be."
