Wayne Rooney got into an online spat with Frankie Cocozza after the X Factor contestant said he had bad breath.

The Man Utd star hit back at the disgraced singer, saying he couldn't sing. Cocozza, 18, who was kicked off the show after taking cocaine, continued to goad Rooney, but was ignored.

The row flared on Friday after the disgraced singer entered the Twitter debate #CelebsThat LookLikeTheyStink.

"Not really a celeb but I bet his pits are stinking, along with his breath @waynerooney," the Mirror quoted Cocozza as saying on Twitter.

Not taking it lying down, Rooney responded with his own tweet. "sorry who are u again. Oh yeah i remember ur the kid on x factor who couldn't sing," he said.
