Jemma Lucy will confront ex-boyfriend Stephen Bear on a new TV show after he was accused of cheating on her during their relationship.
The pair are set to appear on a celebrity version of "Eating With My Ex" on BBC Three, where 30-year-old Jemma will address Stephen's alleged cheating during their 2016 romance.
The show reunites former couples over dinner to pick over the bones of their failed relationships, and will air its celebrity version in the form of a couple of special episodes early next year.
Jemma and Stephen appeared together on the All Stars series of MTV's "Ex On The Beach" in 2015, but only hooked up once Stephen left the "Celebrity Big Brother" house in early 2016.
They dated for several months, with pals saying Jemma had fallen for Stephen shortly before the split, and had even gotten matching tattoos.
Jemma said: "It was very intense, it was crazy, there was loads of partying.
"It was a whirlwind of fun and it was like me and Bear were just in a bubble together and we didn't care about what anyone else thought."
But the pair split in late 2016 after Jemma accused him of cheating on her, when several girls contacted her on social media to claim they'd slept with the tattooed hunk.
Speaking to The Sun's Bizarre TV column, she said: "Bear would always deny it and he'd say they were just jealous and they were trying to split us up.
"I believed him the first few times but then just had a gut feeling and messaged one of the girls back.
"I spoke to her and even met her, and everything she was saying just added up."
In November 2016, Jemma replied to a fan on Twitter to accuse Stephen of cheating on her, when he posted a raunchy Snapchat video of himself in bed with another woman after the couple had split.
When one Twitter user wrote: "I swear @stephen_bear was just loved up with @jem_lucy like last week and now he's with another lass (sic), Jemma replied: "I f***ed him off he cheated (sic)."
She added: "He will cheat on her too babe like he did me! I'm lucky to be rid of him ages ago (sic)."
