Pure hilarity. From the Daily Mail:

Things turned personal on The X Factor on Saturday night, when the normally charming Gary Barlow accused his fellow judge Tulisa of having ‘fag ash breath’.

It came to a head after Tulisa criticised Gary for the song he had chosen for his act Christopher Maloney, saying to him: ‘Gary, how many of these eighties classics are you going to let him keep destroying?’

The charmer has left the building! The attack was most out-of-character for the usually gentlemanly Gary
And Tulisa was as shocked as everybody else by Gary’s out-of-character comment, sitting there open-mouthed as she took in what he had said.

But as Dermot O’Leary spoke to Christopher following the performance, Tulisa interrupted saying: ‘Just a note for Gary – lay off the red wine because I can really smell that as well.’
