Michael Bublé talks about impending fatherhood, Amanda Holden reveals she hasn't spoken to ex-husband Les Dennis about her upcoming autobiography and Jack Dee says he returned to touring to get away from his family.

Michael Bublé, joining the show straight from a 60-hour round trip to Australia, talks excitedly about impending fatherhood, "It worked, the sex worked!"

Revealing that making the baby wasn't particularly romantic, he says, "There was nothing sexy about it. My wife is so beautiful but it wasn't like that. She was very, 'You know what Mike, it's nine o'clock on Tuesday night and we must do it now.' But, you know what's funny, I think when we conceived was actually when we were wasted in Milan and it was the one night we just had drunk awesome sex!"

Discussing the baby's name and seemingly liking Graham's suggestion of 'Graham', he says, "My wife is killing me, we fight about the names. She is Argentinian and keeps coming up with terrible names that she thinks sound good in Spanish, like 'Dirt'... Dirt Bublé!"

Revealing he sings to the bump, he says, "I was doing it early on, really early on and I didn't know 'cos I've never had a baby before and in the middle of singing my wife starts laughing and says, 'the baby is two months and has no ears to hear you!'"

Demonstrating his technique, Michael delights two pregnant women in the audience by serenading their unborn babies.

When complimented on his new album he jokes, "It's not great, it's okay but honestly, I wouldn't waste your money. Download it illegally, trust me," adding, "There's someone from the record company backstage having a fit now." He adds sweetly, "Actually, I love it, it's the best thing I've ever made before I made the baby."

Amanda Holden, talking about her upcoming autobiography, which is due out in September says, "I'm still doing it. It's torturous but I am coming to the end. I'm not doing an index because everyone looks for themselves and they don't read the book. I've known Simon Cowell for 10 years and I'm one line in his book, I didn't buy it, I just looked in the index!"

Deciding on a name for the book proved problematic, "I've got so many names. Holden just lends itself to so many headlines - if had a face lift I could have called it Holden Back the Years, or I thought a genuinely good name was No Holden Back. I have got my name in it, but I can't tell you."

Talking about whether she will reveal all, Amanda says, "I'll be telling lots of things that you don't know. It will have stuff that is surprising to hear, but also my children will read it and I want it to be a legacy for them. I don't want it to be a trashy book. I won't be trashing people but I will be telling a few home truths."

Asked if she has talked to her ex-husband Les Dennis about the book, she says, "No, because he didn't talk to me about his. We were married for 10 years and we were in love but I've never told my side of the story, ever, so it will be very interesting to hear." And, on whether her side of the story will be very different to his, she says, "I think he was pretty fair. I didn't read his book but I had someone that did to make sure we didn't have to sue and stuff like that."

Jack Dee, talking about returning to touring after six years, says with his trademark deadpan deliver, "I was doing other stuff and then I wanted to get back and spend less time with my family so started to tour. Relationships from a distance are far easier. It's just, 'Miss you too,' send. And it's done. It's a stress free existence."

Michael performs It's a Beautiful Day from his new album live in the studio before helping Graham and Amanda pull the lever on more foolhardy members of the audience brave enough to sit in the red chair.
