Graham is joined by Hollywood star Jack Black, talking about his new film Gulliver's Travels; comedian Miranda Hart, who talks sitcoms and pratfalls; maverick film-maker and Hairspray creator John Waters; and pop sensation Justin Bieber, who sings his latest single.

Graham is joined by pop sensation Justin Beiber, Hollywood actor, Jack Black, funny girl Miranda Hart, and filmmaker John Waters.

Congratulated by Graham on receiving two Grammy nominations and heralded as the most famous person on the planet, Justin says: "I can still do normal things but just not in a normal way."

On loving girls he says: "I like all girls... someone who is funny, nice personality and nice eyes."

Demonstrating his flirting skills, he delights his female fans in the audience with his British accent and says: "I like English accents, they are so sexy."

Justin, talking about his mother, says: "Mum goes everywhere with me. Sometimes I need time away from her so I book her into a spa as a gesture of love so I can have some time on my own. She disciplines me and definitely still keeps me in line. The other day, we got in an argument, and I was a bit disrespectful. She tried to take my phone as punishment, and I said no, so she just cancelled my (phone) plan."

Jack, on his new movie Gulliver's Travels, says: "We've modernised it a bit and brought in some new flavours but it stays true to the original humour. It's a 3D extravaganza. My stomach is coming atcha!"

He adds: "The truth is I haven't actually seen myself in 3D yet. I've seen the film in 2D like 34 times as I'm a producer. On working with British actors, Billy Connolly, Catherine Tate and Chris Morris, he says: "I was impressed."

He also compares himself to Susan Boyle asking the other guests: "Can you see a resemblance? I think me and Susan could play brother and sister in a movie sometime. It could be sitcom!"

Miranda talks about the success of her sitcom and on her single life, admits: "I use twitter for advice. Various things including my smelly dog. Well it's quite good for getting advice when you live alone."

John Waters talks about his new book and his creation of the phenomenon of Hairspray. On his childhood he says: "I wanted to be a teenager with problems but I didn't have any. I really wanted braces so I wedged paper clips in my gums."

And finally, Graham pulls the lever on foolhardy members of the audience brave enough to sit in the red chair.
