Washington, June 16 (ANI): Russell Brand has blasted Graham Norton for enquiring about his failed marriage to Katy Perry in front of his mother, which left her teary eyed.

After the 49-year-old presenter made the query, Russell refuted the claim that the issue 'just came up'.

He said: 'It did not come up, mate. You brought it up.'

Talking to fellow guests Emily Blunt and Paloma Faith, the 'Rock of Ages' star claimed that Graham betrayed him.

'He upped the stakes and stabbed me in the back. My mum is here. She got upset earlier when you dragged up my marriage. I saw her cry, Contactmusic quoted him as saying.

'That's reality because it's real people, Graham, that's my real mum. That's why I was a little bit embarrassed when I saw my mum crying. I came here to promote a film and you made my mum cry. I don't see you as that sort of person, Graham.'

Brand asserted that Norton should have warned him before filming, that he would mention his divorce that took place just after 14 months of marriage to Perry.

'What I would have done mate is come up to me before the show and gone: 'Eh, listen. It's a bit odd that your ex-missus was on last week. I might mention it. Is that OK?' And I would have gone: 'Of course it is.'But in all of the chatting and the research, no-one mentioned it, he said.

However, Norton refuted the accusations and insisted that it would have been weird not to enquire about the comedian's marriage, as Perry made an appearance on the show last week.

'If I had not asked anything it would have been weird because Katy was on the show last week. That's the only reason, he said. (ANI)
