Jennifer Lopez talks about her risqué performance on Britain's Got Talent, Freddie Flintoff explains the finer points of cricket to Jennifer and reveals what happened when he met the Prime Minister, David Mitchell says Victoria Coren is the best thing that has ever happened to him and the stars of musical Once perform live in the studio.

Jennifer Lopez, talking about the response to her risqué performance on Britains's Got Talent, says, "It got a reaction. I wore the exact same outfit for the Billboard awards a week or so ago and there wasn't a peep from anyone. Perhaps the outfit in black made a difference." Talking more about her daring outfits, she says, "I trust myself; look in the mirror, look front, look back and out you go."

Talking about her five year old twins, she says, "They are the best thing. They usually travel with me everywhere. But this time they are with their grandma. It was a little heartbreaking for me. It's hard to not be with them."

And on bringing up both a boy and a girl, she says, "From when they were really small I could the differences between them. It really highlights the differences between men and women from the get go. Women think, or tend to over think, and men do not think at all. I actually understand men and women more and it makes it easier to forgive guys."

Asked if it was awkward being directed by her choreographer boyfriend Casper Smart in her latest video, she says, "No. It's fine, we kind of collaborate." Asked if that means she does exactly what she wants, she says, "A lot of the time!"

Talking about her new film, Dance Again, she says, "I went through a particularly rough time in my life when I got divorced and the film is quite a journey. It's about picking up the pieces after something terrible happens. It's a little bit revealing and actually I have freaked out a couple of times about it already because of how much you let people into your life. It's something you struggle with as an artist."

Freddie Flintoff, talking about his children, and asked if they remember him playing cricket, says, "The boys have no idea what I do. They think I work for Morrisons because I did an advert for them." Revealing some concerns about his children finding out about his well-publicised drunken antics, he says, "When you have kids you don't think of Google. When they are old enough to search my name, I'm going to have some explaining to do. It's going to be a tricky time."

Talking about one such incident, Freddie reveals what really happened at 10 Downing Street the day after winning The Ashes in 2005, "After the match I decided to go to the hotel bar with a few mates and it was 8.30 in the morning before I knew it. My wife put me in a blazer and tie and I thought I was going to school or something. We then got on the tour bus and there were hundreds of thousands of people and I thought the sales must be on because it was so busy. I had no idea what was going on.

"We get to 10 Downing Street and I asked Cherie (Blair) where the toilet was and I had a wander round the house and then I got kicked out of The Cabinet Room. I was sat at the head of the table pretending to be the Prime Minister. I had my feet up on the table saying things like, 'What about you, Home Secretary?' And the guard came in and said, 'Alright Freddie, you've had your fun, get out.'

Talking about the 2012 professional boxing match he won, he says, "I'm not particularly aggressive. Before I started boxing I should have looked a little bit more into it because I don't like being punched and I don't like punching people. The chap I fought was from America and he'd been sent down for GBH and had been shot four times and then he asked about me and I said, 'I used to play cricket, we used to stop for sandwiches!'" Asked if he would do it again, he gives a very firm, "No."

Asked if it's hard watching cricket instead of playing, he says, "I still miss it, I think I will miss it when I'm 50 or 60 as it's what I've wanted to do since I was a child."

Trying to explain the finer points of the game to Jennifer, who has never heard of cricket and is somewhat confused the rules, Freddie says, "It's hard to explain, but basically, it lasts five days, we break now and then for food and we spend a lot of time rubbing our balls on our trousers."

David Mitchell, talking about his wife (Victoria Coren) and her professional poker playing, says, "I've been to watch her play a bit but you can't see what cards everyone has so it's incomprehensible, but I watch enthusiastically."

And on including Victoria in his memoir, he says, "Meeting my wife is the best thing that has ever happened to me and it seemed like a very nice way to finish the book. A lot of what I talk about and what I find funny come from a feeling of weird self-doubt, anger and awkwardness so it's quite nice to include something that has gone so very right."
