Irish singer Ronan Keating fell victim to internet pranksters on Monday (08Oct12) when his Twitter.com page was hacked.

A message promoting weight loss popped up on the When You Say Nothing at All hitmaker's page, and Keating was unimpressed that his account had been illegally accessed.

In a post, he writes, "Last tweet about diet product was not me. Think I have been hacked. Don't know product and I don't endorse it."
