Irish singer Brian Mcfadden has offered up a reward in a bid to find the hoaxer running a Twitter.com account in his name.

The former Westlife star sends messages to fans on the site using the handle @BrianMcFadden, and he is keen to have the unofficial @brianmcfaddenn page shut down.

McFadden revealed on Friday (12Jul13) he is offering up $1,000 to anybody who can help him find the person behind the fake page.

In a post on the site, he writes, "Anyone who knows who owns and runs the hoax Twitter account @brianmcfaddenn let me know. $1000 reward if you do."
