The presenter of Sky1’s new search-for-a-star talent show Must Be The Music (Sunday, Aug 15) talks music, mountain-climbing and… painting Cheryl Cole!

What makes Must Be the Music different from other talent shows?
”It’s about people who care about music and are naturally talented, rather than people who just want to be famous. There’s a real mix of genres and they all either do their own songs or perform a cover with a twist.”

What do the judges bring to the table?
“Dizzee Rascal has come up via the underground route and is quite tough, Sharleen Spiteri manages bands and knows rock music inside out, and Jamie Cullum has a finely-tuned musical ear, but finds it hard to be mean to people.”

Did you have any particular favourite auditions?
“A couple of girls who are best friends were extra-special, and I cried when I watched them. There’s also a guy who has invented this bizarre trumpet-like instrument, which was a sight for sore eyes.”

How would you do on the show?
“I would be absolutely horrendous as, although I am obsessed with music, I have very little musical talent. I am not a good singer and I play the guitar really badly.”

You’ve interviewed lots of famous people over the years. Who has impressed you the most?
“Princes William and Harry. I was incredibly nervous and thought they would be aloof, but they are two of the nicest people.”

Do you still get starstruck?
“Oh, massively. I met Robert Plant recently, who is one of my all-time heroes, and I just couldn’t believe I was chatting to him. It was like an out-of-body experience. I think I managed to say about two words and just giggled my way through the rest of the interview.”

What would you have done if you hadn’t become a TV presenter?
“I wanted to be an air hostess and I wrote to British Airways when I was six years old and got a reply. I have an art background and my dad is a graphic designer, so maybe I would have put that to use.”

You still paint, don’t you?
“I paint large portraits in my spare time, and I often do little five-minute ones of celebrities to keep my hand in. I showed Cheryl Cole hers, and kept saying: ‘Don’t get freaked out, I’m not a weird stalker.’”

What is the biggest misconception about you?
“After doing kids’ TV it took a while to shake the bubbly blonde image. I used to get a lot of ‘rock chick’ headlines, but I am so un-rock chick. I like sitting at home reading or being with my cats.”

What are you proudest of in your career?
“Anything I do for Comic Relief stands out because it really means something. After the Kilimanjaro climb, I had a great sense of achievement.”

Will you be doing Gary Barlow’s trek to the North Pole then?
“I will definitely think about it. I usually get talked into these things, and Gary and Richard Curtis together are a very persuasive combination.”
