Producers are said to be hoping the former 'Love Island' contestant dishes the dirt on her relationship with Marcel Somerville - who broke Gabby's heart when he slept with another woman behind her back - when she enters the famous abode for the Channel 5 reality show later this year.

A source said: "Gabby was devastated when she found out Marcel had cheated on her.

"She really thought he was the one and has been left heartbroken by what he did.

"Doing something like 'Celebrity Big Brother' was never on her radar, but after their break up she wanted to do something challenging to help push her out of her comfort zone.

"Enough time has passed now and she won't be afraid to tell all about their failed relationship and the effect it had on her."

'CBB' returns to screens in August, and Gabby is said to be hoping that the experience of being isolated from the world with "no phone or social media" will help her put her relationship behind her and get over the former Blazin' Squad star - whom she met on the 2017 series of the ITV2 show - once and for all.

The insider added to The Sun Online: "Being cut off from the outside world with no phone or social media will be like an intense form of therapy for Gabby.

"She'll have plenty of time to think and won't hold back when it comes to revealing

"She thinks it'll help her get over Marcel once and for all."

Gabby seeking closure through the show fits in with the theme for the upcoming series, which is said to be "retribution".

Meanwhile, Stormy Daniels, 'Queer Eye' star Jonathan Van Ness, and comedy duo The Chuckle Brothers have all been tipped to be entering the house for the upcoming series.
