Comedian Russell Brand was left furious after chat show host Graham Norton quizzed him about his divorce from Katy Perry on his programme – saying that he had upset his mother.

Brand, who was appearing to promote his new film Rock Of Ages, lost his temper on camera after Norton – who recently had the singer as a guest on the show – brought the subject up.

“My mum is here. She got upset when you dragged up my marriage,” he said. “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,” he added. “I don’t see you as that sort of person, Graham.”

The presenter attempted to defend himself, saying it would have seemed “weird” if he had said nothing – but Brand hit back, saying, “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.”

A source later told the Mirror, “Graham didn’t mean to upset Russell but felt he had to ask at least one question about Katy.

“Other journalists have quizzed him on it all week so perhaps he’d had enough.”
