Russell Brand has hit out at Graham Norton after the talk show host asked him about his failed marriage to Katy Perry.

The 37-year-old, who filed for divorce from the 'California Gurls' star last year, lost his cool after the Irish comedian mentioned his former partner during an interview on BBC’s The Graham Norton Show.

He said: “My mum is here. She got upset when you dragged up my marriage. I saw her cry, Graham. That’s the reality because it’s real people, Graham, that’s my real mum.

"I have come here to promote a film and you made my mum cry. I don’t see you as that sort of person, Graham.”

Norton, who had previously interviewed Perry on last week’s show, then replied: “I don’t see myself as that kind of person. If I had not asked anything it would have been weird.”

But the Arthur star continued to vent his frustrations, adding: “Will people sit and think ‘Oh that’s odd?’.

“What I would have done, mate, in your position is come up to me before the show and gone ‘Eh, listen it’s a bit odd your ex-missus was on last week. I might mention it, is that OK?’

"But in all of the chatting and the research backstage, no one mentioned it.”

Norton, who was also joined on the sofa by Paloma Faith and Emily Blunt then apologised, saying: “Well, I’m sorry.”
