After winning Love Island 2017 and walking away with £50,000 prize, Kem Cetinay and Amber Davies called time on their relationship late last year.
They’ve since spoken out about the split, insisting it was a mutual decision and explaining they still care for each other.
But now Amber’s revealed she’s received multiple messages from women claiming to have slept with Kem.
"I felt like I'd been stabbed, but Kem was saying he was bleeding,” she told The Sun.
“I've had a handful of messages from girls - some sent just a few days after we had split - saying they had slept with him.”
She added: "People deal with things in different ways, maybe that was his way. But if I was sleeping with loads of people, I wouldn't speak publicly about how heartbroken I was."
Kem has also been linked to former Gogglebox star and Queen of the Jungle Scarlett Moffat following the break-up - and Amber even hinted toward the romance on Twitter.
After someone tweeted: "Definitely something going on between Kem and Scarlett Moffatt #DancingOnIce", Amber replied: "You said it 😋".
Meanwhile, rumours were flying around that Amber had been growing close to The Only Way Is Essex star Pete Wicks.
Despite the reports, Amber previously revealed the truth behind her split with Kem during are appearance on Lorraine.
She said: "I think it was just so intense and it was a mutual decision. It did fizzle out because we were so busy. But we're still really good friends."
