Westlife don't see each other anymore.
Asked if he still meets up with the rest of the group, Kian said: ''Not really. I saw Mark briefly just after Christmas.
''I'm sure the time will come when we'll sit down for a beer together, but right now we need to go off and live our own lives.''
It had been speculated that the group will reunite next year, but Kian is ''baffled'' as to what sparked the rumour because it isn't true.
He told Britain's OK! magazine: ''It's completely untrue. It baffles me as to why people make these things up.
''If Westlife ever reunite, we'll tell people, but it's not on the cards.''
Despite Kian's comments, his ex-bandmate Brian McFadden - who quit the band in 2004 - has suggested a reunion involving himself could be on the cards.
Asked about rejoining the band in a separate interview with the same publication, he said: ''Never say never, but right now it's just a rumour. Rumours like that will be around for a long time.''
It's time for a riot grrrl revolution.
