One Direction star Niall Horan and Victoria's Secret model Barbara Palvin were spotted leaving the X Factor wrap party at Marylebone One club.
The 20-year-old, who performed with his band members Harry Styles, Liam Payne, Zayn Malik and Louis Tomlinson for the show's finale, was also seen getting cosy with her backstage.
Previously Horan was seen golfing with Palvin and a few other friends.
TopGolf UK tweeted: "@NiallOfficial thanks for dropping in to see us last night! No stopping @BarbaraPalvin #smashedit #winner See you again soon :))"
However, the singer's mother told Ireland's RTE station that she doesn't think that he is ready for a serious relationship.
"I don't think Niall is ready yet for a serious girlfriend. He's a real happy-go-lucky lad. He wants to enjoy life and isn't ready to settle into a steady relationship as far as I know just yet," she said. "He's a good gentle character himself. There are in that position where they'll meet lots of people and girls. A girl he'll go for dinner with here and to the pictures with there - but I'm not sure they are all girlfriends... When he has something to tell me, he'll tell me."
Palvin was previously romantically linked to Justin Bieber, after the Canadian pop star's then girlfriend Selena Gomez retweeted a photo of Palvin and Bieber together at the annual Victoria's Secret Fashion Show. However, the Hungarian beauty said she and Bieber are just friends.
"You know how the drama started -- Selena retweeted the picture," she told Celebuzz then, "I'm okay to talk about it because I know there's nothing. It's ridiculous how this got to the news."
"That was it . . . that's why it was so weird. They thought I caused a big drama, their break-up," she added.
