Irish singer Brian McFadden has launched a foul-mouthed tirade on his Twitter.com page attacking "cyber bullies" who stalk him online.
The former Westlife star was fuming when one fan posted a string of derogatory messages aimed at him, including poking fun at him for not getting an invite to the Grammy Awards.
MCFadden decided he'd had enough of the torments and outed the Australian user, named JohnRiot, on the microblogging site, before challenging him to a fight.
In a string of messages he fumes, "Your a c**t face. If you want a go let's do it. I live in woolloomooloo. You know where I am. Bring it on juice junkie. One on one... Hey steroids face johnriot I am absolutely up for a one on one pikey fight. You have insulted me and my family. Let's end this!!! JohnRiot come on you old lesbian. Put your f**king money where your juiced up mouth is!!!!!
"F**k these cyber bullies! Let's take a stand!!!! F**k that. Let's stoop to there (sic) level!!!!
"Come on johnriot speak up. Let's do it. Stop hiding behind the internet. You know who I am and where I am! Stand up."
