Tracy Beaker star Dani Harmer is reportedly struggling with the sexy moves on Strictly Come Dancing.
The Sun quotes a source, who said: "Dani isn’t used to strutting her stuff on stage and is finding that her biggest challenge is trying to be sexy when she dances."
Meanwhile, Harmer, who's been paired with pro dancer Vincent Simon, has responded on Twitter to comments about her weight.
The 23-year-old said that she wouldn't let jibes about her size get her down.
She has also tweeted a picture of her and Vincent looking exhausted during training to her 50,000 followers:
