Gabby Allen has dumped Rak-Su's Myles Stephenson.
The "Love Island" 2017 star called time on her relationship with the "X Factor" 2017 winner - who she's been dating since last September - after she reportedly caught him red handed sending saucy messages to other girls on Instagram.
A source told The Sun newspaper's Bizarre Column: "Gabby suspected Myles had been messaging a girl a while ago, but he told her that one of his mates had used his Instagram account. Then when they were meant to be having space apart, Gabby caught him red-handed. She immediately ended the relationship."
The alleged infidelity comes almost a year since she found out her then-boyfriend Marcel Somerville - who she met on "Love Island" - had sex with another woman behind her back while they were on holiday together.
The insider explained: "She is shocked that it happened, especially after everything she went through with Marcel. She has made her decision and doesn't want to be with someone she can't trust."
Gabby and Myles hadn't been together that long before she moved him into her flat in North London but things had been going from strength to strength and she even admitted recently that she could see herself settling down and marrying him.
She said at the time: "He's amazing. We've only been together a year, but it moved pretty fast and we live together in Islington. He basically came to my house and never left. We can hear wedding bells. We talk about long-term stuff all the time."
Gabby, 27, sparked rumours she had split from the 27-year-old singer earlier this week when she deleted the photo of her and Myles on her Instagram account.
