What can we expect from Greased Lightnin'?
"Well it's kind of a little sister to the main show, so it gets to ask the slightly more cheekily-angled questions. I think we probably dig a bit deeper behind the face value story, and try to see what makes our contestants tick. It's all done with a bit of a wink and a smile."
Are you excited about working with David Gest?
"I'm very excited! He's got real character. I was a big fan of his when he was in the jungle, so I'm intrigued to hear all the stories about his aunties and families and goodness knows what. Definitely - I think he's going to be a fabulous judge."
What do you think of the judging panel?
"I think the judges are a very good mix, because you've got David Ian, who's extremely professional, knows West End theatre like the back of his hand and knows exactly what he's looking for. It's literally what he does. Then you've got David (Gest), who knows how someone should sound as a performer, but also has that little sparky naughtiness about him. Between him and David Ian, they both know what they're looking for and if you put them together, who knows what they'll come up with! Sinitta's just sweet and lovely and, you know, she looks great! I think when David Ian's being slightly harsh, Sinitta's nice to balance it out. And Brian - I laugh at Brian! He's just amazing and he's really gracious - you'll see what I mean when you watch it."
Are you sad that Dancing On Ice has finished?
"Yeah, totally. It's really weird because it's such a massive show and you get so absorbed into it, so when it's over you're like, 'What?' It's weird because you suddenly get your life back a bit. But I'm sad, yeah, totally sad. I think it was the right time for it to finish. The poor celebrities were so knackered - Clare and Kyran and Duncan were like, 'Enough already, we're done'."
Is there are any truth to the rumours that you're going to present a dating show with Fearne Cotton?
"At the moment it's such early days that I wouldn't want to say anything. I don't want to tempt fate because it really is in its early stages. In all honesty, I don't know much about it, so I wouldn't want to say anything and be wrong about it."
Is it something that interests you?
"Oh god, yeah, definitely. I'm a girl - it's my right to set people up! Wouldn't that be amazing?"
Is there any chance of a new series of Holly & Stephen's Saturday Showdown?
"I wish! But no, there won't. ITV has moved all their children's programming to the ITV Channel and unfortunately for them to put a three-hour live show on the ITV Channel isn't financially viable. It's a bit of a shame - I really miss it."
So how have you made a conscious decision to move away from children's TV?
"No...I'm not turning my back on kid's telly at all, but you always want to move on and progress and all that sort of stuff. If the right show came up and I wanted to do it, I wouldn't turn it down just because it was kid's telly. I had the best years of my life on kid's TV."
Who do you most admire in the world of TV?
"I think that Jonathan Ross is amazing - he's just brilliant - but Cat Deeley is brilliant as well. I've watched her career right from the word dot really, and she's just done so brilliantly with all the American stuff and all of that. She's always done it with real charm, and you never read anything bad about her. She's obviously doing something right. I think she's great."
Would you be tempted to try your luck in America like Cat?
"I knew you were going to ask me that! I'm too much of a homebod, and I'm getting married this year so I don't want to suddenly shoot off to America. If there was a show out there for a month, I might go and do it, but if it was a question of moving over there for six months, I don't really think so."
Grease Is The Word begins on Saturday at 6.05pm on ITV1. Greased Lightnin' starts on the same day at 8.40pm on ITV2.
