The female celebrities in this year’s Strictly Come Dancing are not sexy enough according to judge Bruno Tonioli.

The judge told the News of the World that Ali Bastian, who is rumoured to be dating her partner Brian Fortuna, needs to show more passion on the dance floor if they are going to impress the judges and the public:

"She is like a fairy princess in the ballroom but I think she is not quite letting go in other ways.

"She needs to be a naughty girl. I want to see a bad girl doing the Latin.”

Eccentric Bruno also claimed that actress Natalie Cassidy should flaunt her body and her breasts more and use her assets to her advantage:

"I told her, 'They're great, they're gorgeous, and you’ve got to show them'.

"She was always slouching forward. I said to her, 'If you've got it, flaunt it, gorgeous girl - those are votes, I am telling you that.”

He also told the star: “If you paid for them, you might as well use them'. She has got to manage her assets better."

The women on the show sometimes dance in very tiny outfits and the judge seems to think that their performances are not as passionate.

The men in the competition did not avoid the judge’s criticism either. Actor Ricky Whittle and his professional partner Natalie Lowe have been a favourite with the judges, but recently have been warned not to get too complacent as the competition heats up.

Bruno warned: “He is amazing. But he keeps messing things up - I could slap him."

There are five couples left in the show.

Strictly Come Dancing continues on BBC1 at 6.50pm next Saturday.
