One Direction star Liam Payne is a single man again after splitting from his dancer girlfriend Danielle Peazer, according to a U.K. report.

The What Makes You Beautiful hitmaker had been dating Peazer on and off since meeting during his time on the British version of The X Factor in 2010, and after a brief split in September (12), they decided to seal their commitment to one another by adopting a dog together in March (13).

However, it appears they have since chosen to call time on their relationship due to Payne's hectic schedule.

A source tells Britain's The Sun, "They have been trying for months to make it work but it just hasn't. They had a big chat last month and decided there wasn't any point in dragging it out.

"Liam's on tour until November and Danielle's very busy so they basically never see each other. It was extremely amicable though, which is good because there's a strong chance Danielle will still be in the lads' upcoming 3D film.

"The boys are still filming it and editing is going to go right down to the wire. But she's been there for most of the filming so it'll be tough to cut her out and Liam wouldn't want that anyway."
