Sorry, Directioners! One Direction cutie Niall Horan appears to be off the market. The blond singer was spotted getting very cozy with Victoria's Secret model Barbara Palvin.

Horan, an avid golfer, was seen golfing with Palvin on Friday (Dec. 13) and a few pals. However, witnesses the golf course noted that the pair were smooching and canoodling all night, so it wasn't just a platonic round of 18 holes, either.

The staff confirmed that the couple were there:

And then a spy tweeted:

Horan and Palvin were also spotted on a movie date to see 'Catching Fire' recently, though Horan's mom doesn't think they're too serious.

She reportedly said, "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 added, “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.”

The Palvin spottings come just weeks after Horan was reported to be hooking up with British TV star Louise Thompson on the sly. Not bad, Nialler! (And ladies, if Palvin sounds familiar ... it's because she was accused of hooking up with Justin Bieber.)
