Jeremy Renner talks about dancing with Madonna; Gemma Arterton reveals she's quite a fighter; Matt Lucas talks about being mugged; and Delia Smith says the Bakeoff was just a warm up; while Rita Ora gets a date for the Brits.

Jeremy Renner, talking about the upcoming Oscars, confides he doesn't have a date, and asked if he will be taking his mother, says, "I haven't asked her. I felt like a bit of dead weight when I took her before. I was dragging her down because I had to go to the Governors ball afterwards and it's still work, and she was off at Vanity Fair with all the winners - dancing and doing the whole thing. She doesn't need me."

Asked if it was true he danced with Madonna at the same Oscar party, he says, "It was one of those random circumstances where I felt something in my backside and it happened to be Madonna and I'm like, 'hey.' It was nice."

Gemma Arterton talks about her latest movie and the opportunity to do her own stunts, "It's one of the reasons I wanted to do the film because I've always wanted to punch people! It was fun. I had to do lots of training because I had never done anything like it before and I loved it, absolutely loved it."

Revealing how that training came in handy recently, Gemma says, "I was in one of those ATM cash machine rooms and there was a tramp in there. He kept looking at me and then he grabbed my bum really hard. I turned round and properly punched him in the face. I then realise I'd punched a tramp in the face so I ran. Thank god he didn't punch me back. I actually felt quite bad about it."

Talking about her early career she says, "I worked in a South London Karaoke gangster bar. It was a bit dodgy and occasionally I would get threatened. I would get asked for My Way 10 times a night and when I said no, this guy pulled out a crowbar and went for me. 'Honest Dave' the owner saved me and said that if that happened again I should sing My Heart Will Go On, by Celine Dion because it really chills everyone.' It was like a soothing balm over all the drunken gangsters and from then on when it got a bit fraught he would say, 'Gemm, do Titanic.'"

Matt Lucas, talking about his first leading man role in his new movie and having to do an American accent, says, "I got worried about it so I had a dialect coach and I stayed in dialect for the whole of each shooting day. It was quite weird and I had to text my mum to say, 'I'm going to be calling you in a minute and I'm going to be doing an American accent when I do,' and then I called her and said, 'Hi mom' she said, 'G'day mate!'" adding, "It is a very dark and strange movie and I am not letting my mother see it."

Revealing the true story behind his recent mugging, Matt says, "I was in a pub with a friend and an old lady came in selling flowers. She was like a Dickensian impoverished flower seller and wouldn't go away so I gave her a fiver. She then started kissing my hands and thanking me. When she left I realised my phone wasn't there so I ran out of the pub, saw the woman, shoved her against the wall and demanded my phone and the money back. She eventually gave them to me but as I ran away through a crowd of people that had gathered, I realised all they saw was me mugging an old lady for a mobile phone and some cash!"

Talking about living in LA with Rebel Wilson, he says, "People ask if we are brother and sister, or husband and wife or are you one and the same person?" Revealing they aren't always popular with their neighbours, he says, "We got a letter of complaint because we went a bit crazy playing show tunes all night and they started throwing eggs over the fence. I don't blame them actually but we did have Samantha Barks there warbling away so the singing was quite nice. They were getting a free gig!"

Delia Smith joins Graham for a chat about her new project and, in light of the horsemeat scandal, says, "I have to say if you ever wanted to come on television and advertise a cookery school it's this week."

Asked about the success of The Great British Bake Off, she says with tongue in cheek and pointing to her own book, "It's wonderful, but it's just been a warm up..."

Talking about her beloved Norwich Football Club she says, "I wouldn't sell it, but I might have to ask the supporters to see what they would like me to do." Asked if she ever tells the players off when the club loses she says, "Never, I don't say anything."

Rita Ora performs Radioactive live in the studio before joining Graham for a chat about her success and Brits' nominations.

Matchmaking, Matt says to Rita, "Jeremy asked me to ask you if you're single." Feigning embarrassment, she replies, "He didn't? But, I am." When Graham suggests Rita now has a date for the Brits, Gemma confirms Jeremy is free and Rita says, "There you go, I've found a date." And it looks like Jeremy might not be going to the Oscars alone after all...
