Niall Horan's relationship with Barbara Palvin has supposedly 'fizzled out'.
The 20-year-old One Direction began dating the Victoria's Secret model, also 20, late last year.
But new reports suggest the rumoured couple have called off their romantic relationship entirely.
'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 British newspaper The Sun.
Niall is currently in the UK recovering from knee surgery and Barbara has been travelling across the globe for work.
Apparently their packed schedules is the main reason they decided to stop dating each other.
'They are both really busy and Niall is focused on recovering and getting ready for the band's massive Where We Are Tour,' the insider said, noting the pair 'are still in touch and friendly' with each other.
Although Niall and Barbara have yet to formally comment on their alleged split, the model posted an image of a strapping young fellow kissing her on the cheek Tuesday. The stunning brunette seems to have alluded to the fact she is no longer with Niall, as she captioned the romantic image with the mystery man: 'Early Valentine!'
Niall is fast stealing his bandmate Harry Styles' crown as the main lothario of the group, as he has recently been linked to three women - model Barbara, his on/off girlfriend Zoe Whelan and reality TV star Louise Thompson.
And it is claimed Niall is concerned about the reputation he is gaining.
"Niall is pulling his hair out because he just can't make up his mind and feels like he's messing all three girls around," a source explained to British magazine Heat recently.
One Direction's Where We Are Tour will kick off in Bogota, Colombia on April 25.
