Boyzone were reportedly involved in a brawl in Australia with members of singer Rihanna's band.
According to the Daily Mirror, Stephen Gately said: "Well, we did get in to a fight - certainly more than a difference of opinion."
"It was over a girlfriend of one of Rihanna's band members. We just wanted to chat and be friendly and this guy tries to rough us up."
A source told the newspaper: "Her boyfriend took offence and all hell broke loose with fists flying everywhere."
"The boys held their own despite being unsteady on their feet. Security came to break it all up. They got a stern talking to."
