Los Angeles: Singer Niall Horan is single again after splitting from his model-girlfriend Barbara Palvin.
Horan and the Hungarian model, who were dating since December last year, parted ways after they found it difficult to make their relationship work due to their hectic work schedules, reports femalefirst.co.uk.
"There was no big fall out, things just fizzled out as Niall and Barbara are both working in different parts of the world," a source told The Sun newspaper.
"They are both really busy and Niall is focused on recovering and getting ready for the band's massive 'Where We Are' tour," the source added.
However, the duo is "still in touch and friendly", said the source.
Palvin, who is based in Paris, confirmed she has split from Horan by posting a romantic photograph of herself and a new secret boy on her Instagram account, clutching a bunch of flowers. It was accompanied by the caption, "Early Valentine".
