Brian McFadden has joked that he and Ronan Keating need to "take a break" from each other.
The former Westlife star has teamed up with Boyzone's Ronan on several occasions and jokingly told The Sun that they would cut back on their joint projects in case people start thinking there's something going on between them.
Brian, 32, said: "Me and Ronan will take a break from each other now. We've done a lot of duets together and we've done two tours together.
"There are no more plans to do anything else. I think people will start to think there's something going on between us if we did anything else."
Ronan recently recorded a song for Brian's new album The Irish Connection, which also features other Irish stars.
Brian admitted that he had been hoping to get U2 frontman Bono on board for the record.
He said: "I rang Bono but he was away. I'm still waiting to hear back from him. I left him a voice message. I think it was his number. I found it on the back of a toilet door in a Dublin pub."
