Lucy Mecklenburgh hates her 'Tumble' body.

The former 'Towie' star - who recently competed in the BBC One gymnastics competition - no longer feels ''sexy'' after gaining muscles and losing her curves during the gruelling six hour workout sessions for the show.

A source told Star magazine: ''Lucy was happy with her body before training. The gruelling gymnastics have transformed her shape and she doesn't feel as sexy as she did.

''She doesn't feel in proportion any more, she has built muscle and lost her famous figure. She feels all the hard work she put in to get her dream body has been reversed and she'll struggle to get it back to how it was.''

Lucy, 23 - who came fourth in the final of the show last weekend with her professional partner Billy Jacques - is even struggling to fit into her clothes following her six week stint on the show.

She said: ''I've lost my boobs and my bum has got bigger!

''I've lost 2.5 inches on my hips, 1.5 inches on each of my thighs and I've also gained lots of muscle as well. I put on a pair of trousers and they just fell off me.''

An insider even claims that Lucy is worried about starting a relationship while she comes to terms with her new image.

They said: ''Lucy would love to have a boyfriend, but she's not feeling good about herself. She wants her old body back.''
