The 48-year-old presenter - who hosts the BBC Latin and ballroom show with co-star Tess Daly - admitted she is always the last person to find out which celebrities are competing after previously revealing the secret during an appearance on 'It Takes Two'.

She told 'The One Show': "They brought me in and they said, 'We’re going to give you the list and we’re going to give it to you quite early but you can’t tell a single soul' and I was like, 'Of course I won’t'.

"And it was very important, we passed around crisps and they told me the names and then I went off with my little backpack and got in the lift and someone said: 'Oh don’t you do the sister show, who is taking part?'

"And I told them the whole … I was like 'This, this, this and this, won’t they be good if they danced with so and so?'

"It was not his fault, it was mine, and the next day he went 'By the way, she’s a bit leaky', so now they tell me nothing."

Claudia has appeared alongside Tess for eight years now, but she recently admitted she has a severe case of imposter syndrome and often fears she will be sacked.

She said: "Every day I am waiting for the phone call to say, ‘Dude, we made a mistake'. I have been too lucky, right?"

And although Claudia claims to be a terrible dancer, she hasn't ruled out taking part in the show as a contestant in the future.

She said: "You haven't seen me dance, but if you did you would be physically sick. I don't know. Never say never."
