Niall Horan and Selena Gomez were "very touchy-feely" at the 'X Factor' wrap party.
The One Direction star took his rumoured girlfriend to the celebration to mark the final of the British talent show and spent the whole evening with the 'Heart Wants What It Wants' hitmaker.
A source told The Sun newspaper: "They spent the entire night locked together and were very touchy-feely.
"They kissed in a corridor. There is no doubt there is something going on between them."
The 23-year-old beauty - who sneaked through the side door at the party - spent Sunday evening (13.12.15) watching the chart-topping boy band in one of their last televised performance's before their 18-month hiatus.
However, in the past, Selena has been quick to deny that the pair are in a relationship.
When asked if they're a couple, she said: "Oh my god! No [but] I love him, I always have. He's amazing."
The news is unlikely to please her former flame Justin Bieber, as he previously admitted the pair "could possibly" get back together.
When asked if they'd ever rekindle their romance, he said: "Maybe? We have a lot of history together and I am sure it could possibly happen.
"I think we are both just on our own journeys and figuring ourselves out and I think maybe once we figure ourselves out we can come back and make an awesome duo or she finds someone awesome and I'll find someone awesome. I just want her to be happy."
