Ant & Dec talk about their 25-year friendship, Jamie Dornan says Fifty Shades of Grey has changed him physically, Aaron Paul talks about leaving Breaking Bad, Naomi Campbell denies being a diva and Ellie Goulding says performing for William and Kate was unreal.

Ant & Dec, talk about their new series of Saturday Night Take Away. Asked about the new Little Ant and Dec, they say, "We had to get new ones as the old ones got bigger than us!"

On making Gordon Ramsay fume during a prank for the show, Dec says, "We were lucky. We did think he might be really nice about it but he loses it completely. Thankfully we got Ramsay x 10!" Ant adds, "The lawyers are still counting the bleeps!"

Talking about their early pop careers and how they much prefer the luxury they now enjoy on tour, "We played awful venues; night clubs, under 10 discos and truck festivals. The girls would scream and their boyfriends would stand on the balcony and throw ashtrays and ice cubes at us."

On their enduring 25-year partnership, Ant says, "There is no pressure on us to get on as our friendship comes first and our careers second." Talking about living so close to each other Dec says, "We tried living further apart but it didn't work."

Aaron Paul, talking about his Breaking Bad character Jesse Pinkman's catchphrase, he says, "I get called 'Bitch' every day and people ask me to call them it. The other day a grandmother who had to be pushing 90 asked me and I did. It felt so wrong and yet so right!"

Asked about leaving the show after seven years, he says, "It was very hard for me to say goodbye to Breaking Bad. It was such an incredible family that I love dearly."

On playing Jesse Pinkman, a character that he describes as 'an unbelievably tortured, lonely and sad' and whether he was able to leave character at work, he says, "For the first couple of seasons I lived and breathed Pinkman 24/7 but I learnt from Bryan Cranston who played Walter White, that it was okay to leave the character on set and not take it too seriously. So for the final four season I would unzip that skin and leave him there."

Jamie Dornan, also talking about playing a dark role of a serial killer in The Fall, says, "It's a brutal head space to maintain. It's not healthy, so I made a point of getting out of character - I definitely didn't want to take him home!" On working with the actresses that played his victims in the series, he says, "I was doing the creepiest things imaginable so I kept apologising to them. It wasn't easy for them and I was very aware of how hard it was so I kept saying sorry during horrible scenes."

Talking about his upcoming role in Fifty Shades of Grey and asked if he thinks it will be a massive hit, he says, "I've no idea. We are in a powerful position because 90 million people read the book - it's a nice position to be in."

Revealing the role changed him physically, jamie says, "I always had a complex about the way I walked and people would comment on it. I walked on my toes and when I did The Fall, the director asked, 'Is that part of the character or just the way you walk?' My wife tried to help by making me lean back (Jamie demonstrates much to the audience's amusement) and then in Fifty Shades my character has to dance the fox trot and the teacher said, 'Do it as though you are walking; heel to toe.' No one had ever told me that was how you walk and now I am applying it every day!"

Naomi Campbell joins Graham for a chat. Talking about the seemingly long gaps between her catwalk appearances she says, "I only work for my friends and do one show per season. I feel for the girls now. The shows are tough."

Asked about press rumours about her diva-like behaviour on the set of The Face, she says, "I am thick skinned and I don't read newspapers but I am not a diva." Denying she tapes her face back under a wig (another recent press assertion) she says, "I tape my boobs, not my face."

On whether it's true she doesn't speak to anyone when working she says, "I keep a boundary because there is work to do so when I am modelling or executive producing I don't speak to anyone. I say hello and I am nice to the lighting and sound guys because I know they can mess me up."

Denying she is intimidating, she says, "I'm just a girl from South London. People that know me know I am just the same. The men that are intimidated by me I'll never know them and our paths will never cross." Asked what impresses her in a man, she says, "They have to have a great sense of humour and they can't take themselves too seriously. Life is too short and I want to have fun."

Asked about The Face and whether her friend, and fellow supermodel, Kate Moss will be part of the UK show, she says, "Don't ask me to tell secrets. Kate's been the biggest supporter of the show, she loves it, and of course I would love my buddy to be on it." Talking more about Kate, she says, "Our work has never got in the way of our friendship. We are happy when we work together, it's fun."

Ellie Goulding performs Goodness Gracious live in the studio before joining Graham for a chat about winning a Brit and performing at the Palace.

Talking about her recent Brit award, she says, "It was a big deal. Genuinely I didn't think I'd win and I didn't prepare anything, I was really shaking. It was scary but very, very cool."

And on performing at William and Kate's wedding reception she says, "I still don't believe it really happened. I have no idea how it happened. I thought I might have been a decoy for someone bigger like Lady Gaga or Beyoncé!"
