X Factor 2017 contestant Matt Linnen is reportedly 'smitten' with mentor Nicole Scherzinger.
The Overs performer was voted through to the next weekend last night after singing a cover of George Michael's Careless Whisper.
And sources claim that dad-of-three Matt has been enjoying his time with Nicole.
An insider told The Sun newspaper: “He thinks she is amazing and he hasn’t been too subtle about showing it."
The news follows claims that Matt and fellow X Factor finalist Grace Davies had got together at the contestants' house.
It was reported last weekend that the pair had hooked up behind the scenes.
"It was basically just for fun," a source said of their reported fling. "They now act as if nothing has happened."
However according to the Daily Mirror this weekend, Matt has now 'ended' whatever he did or didn't have with Grace.
A source explained: “Grace and Matt had a bit of a thing together, but he ended it and she is devastated. They hooked up in the kitchen on one occasion, and it looked to everyone else as if they were developing feelings for one another, but Matt cooled things off.
“There’s a bit of an atmosphere in the house, now."
Meanwhile, The Sun report that Nicole and Matt were seen getting "flirty" off camera at an after party following last weekend's live show.
A source revealed: “They get on really well and are pretty flirty with each other, though obviously it’s all innocent as Nicole is still seeing her boyfriend."
The X Factor 2017 continues Saturday night at 8:10PM and Sunday at 7:30PM.
