Luke, 24, was accused of going behind Demi’s back with a student he met on Tuesday night during a PA at a Cardiff club after pictures surfaced online.
According to Mirror Online, a friend alleged they spent a few hours in the club “getting to know each other” before she went back to Luke’s room in a nearby hotel where they recorded a birthday message for one of her friends.
But a source close to the former heating engineer has shut down the report, telling the website that they were also joined by another male friend. "Luke is aware that there are rumours he cheated doing the rounds on social media, but there's no truth to it," the source said.
"He didn't sleep with this woman or kiss her, and the video he filmed with her was a birthday message she wanted him to record for a friend."
They added, "The woman didn't stay the night with him and nothing happened between them. Demi is aware of the rumours and are no issues there."
It comes as Demi told fans they’re closer than ever since leaving the villa. During an Instagram Q&A on Wednesday, the 21-year-old shared: "Me and Luke are doing so good since leaving the villa, I actually feel like we've become closer.
"I don't really know how that's happened because we're not together all the time, but distance makes the heart grow fonder."
And just last night she posted a cosy selfie of them together in bed. Luke M and Demi - we stan!
Cosmopolitan UK contacted Luke’s representative who declined to comment.
