Jessica Wright is said to be "furious" after finding flirty text messages on her boyfriend's phone from another woman.
Finding the messages on Ricky Rayment's mobile whilst the pair were at Jasmin Walia's Diwali party at the Sugar Hut on Sunday, things got explosive between the couple - and all in front of the cameras.
Speaking to the Daily Mirror a source said: "Jess is furious. Ricky has cheated before, so this is totally unacceptable to her."
The pair first found love two years ago, but have faced relationship troubles after Ricky was exposed as a cheater last year on the series, and was forced to deny claims he'd slept with X Factor contestant Lottie Lou.
Now he's in hot water once more with another X Factor contestant in the spotlight, 21-year-old Lydia Lucy.
The source added: "She found flirty messages between him and Lydia and it felt like history repeating itself.
"She confronted him during filming, which really upset Ricky. He felt she could have asked him off camera, so it got his back up."
The exchange between the two is to air in tonight's episode of The Only Way Is Essex, and is set to leave the couple's future in question.
"It was heated - they were screaming. She expected him to just apologise but instead the row could end their two-year relationship."
