Gerard Depardieu reveals all about being caught short, Damien Lewis talks about dinner at the White House, Olly Murs says he did ask for Cheryl Cole's number and Dominic West says he has got away with not being buff.

Telling all about the recent unfortunate incident on an Air France flight, Gerard Depardieu says, "Of course it is true, but the press reaction was unbelievable. When you need to pee no one can stop you, you could die. I tried to use a bottle but there was too much and I said, 'don't worry I will clean it up.'" Cheekily adding, "I felt much better when I did it!"

Despite making more than 180 films and being Oscar nominated, Gerard says, "I don't know how it happened. I don't think I am a good actor."

Gerard confirms that bizarrely he does own an oil field in Cuba, and talks about his unlikely friendship with Fidel Castro, "I met him 1992 when I made him pâté. He loves to eat also, and is very curious about food. He is a friend and I go hunting with him and with Raúl. They know everything about everything and they are normal people."

Talking about his love of food and wine, and revealing a broken tooth, he says, I lost my tooth on a piece of a Jamie Oliver recipe." Damien Lewis interjects, "That's al dente for you!"

Asked if he watches his weight, Gerard says, "No, I don't worry about my size, everyone ends up horizontally dead, I don't give a shit about that. I am wonderful like this." And on his love of food, he says, "I love meat and I love animals. I love to kill something and make a good dish and share it, like love. I am always nice with the animals. But the only animal that is hard to kill is a pig because they are like dogs."

Damien Lewis reveals he has wanted to be an actor from a very early age, "I used to do silly voices in front of the bathroom mirror as a 10 year old, pretending I was being interviewed by Terry Wogan. He would ask me to do different accents."

On his legion of fans - Damien Bunnies - he says, "I got knickers from them. It was a globally coordinated knicker-fest. 40 pairs of knickers were sent. There were granny pants from Wisconsin and cheeky little feathery thongs from Australia. It was very odd. When I chucked them out, someone went through all the rubbish and there was literally a trail of knickers down the street."

Refusing to give away the storyline of Homeland, he says tantalisingly, "It will be psychologically and emotionally devastating. People will be satisfied, there will be resolution of a kind and there will be one or two surprises along the way. It leaves ifself open to return." Asked if he will be in season two, he says, "I can't tell you that."

Revealing that President Obama is a huge fan of the series, Damien says "It turns out it is his favourite show," excitedly adding, "but the big news is that he has invited me to The White House for dinner. I am going with Helen my wife to dinner next Wednesday. I am going to fly to Washington, have dinner and fly back. There will probably be a 1000 of his closest friends but I don't care. I am going."

Asked if he will be hosting Xtra Factor, Olly Murs says "Well, possibly. I don't know. I would love to do it. It's a matter of figuring out dates and schedule but I think I pretty much will be doing it. I hope so."

He also reveals that he did ask Cheryl Cole for her number, "She tweeted me so I thought, 'Sod it why not ask for her number.' You can't blame a guy for trying. Her wifi must be down or something as I haven't heard from her yet."

Confirming he is "100% single", Olly says "I don't sleep with stunning women. Before I got famous no good looking girls would come near me. And now I get loads of gorgeous girls come up to me which is incredible but they only want one thing, to sell their story. I am not that kind of guy. I think they are after money rather than me."

Revealing he has just bought a place of his own, Olly says, "It's just 10 minutes from home so I can still go back for my washing and ironing." And talking about his mother, he says, "She is an eBay seller and sells all my clothes becauses she says I don't pay rent often enough."

Joining the show straight from filming, Dominic West talks about his role in his new film John Carter and being physically toned for the part, "I am not buffed up but I got away with it. It was mainly armour and tattoos."

Reluctantly talking about having gone to Eton, Dominic says, "It is a label that sticks with you. 'Old Etonian' is a stigma that is slightly above 'paedophile' in the media in a gallery of infamy."

Recalling his wedding day, Dominic says, "I became 'Bridezilla' and it became 'The Dominic West Show'. I did everything I had ever wanted to do and got it off my chest. My wife was a reluctant but supportive spectator really."

Olly performs Oh My Goodness from his new album live in the studio.
