The 25-year-old beauty has her own fitness company Results With Lucy, and while her online venture has seen thousands of women sign up in a bid to shed the pounds, she thinks her former 'Only Way is Essex' co-star is too stubborn for her to be able to use her methods to overcome her much-publicised battle with the bulge.

She said: "I would take her on but Gemma is Gemma and she has to do things her own way. I think I would struggle to help her lose weight.

"When she puts her mind to something, she's really determined and ambitious - she's done really well with dieting before - but I think I'd probably let her do her own thing."

However, Lucy would be willing to rise to the challenge if Gemma asked her for advice.

She added: "I'd be more than happy to help if that's what Gemma wanted though."

Meanwhile, though Lucy was recently rumoured to have a new boyfriend, the brunette star - who previously dated Gethin Jones, Louis Smith and Mario Falcone - insists she is keeping her personal life private from now on.

She told Closer magazine: "I've been in the public eye since I was 19. I've found having public relationships and break-ups really tough.

"No one ever knows what happens apart from the two of you.

"Things get exaggerated, rumours start, lies are told. But I've learned from my mistakes and I want a low-key thing now...

"I've made the decision to keep my love life private from now on - but I'm really happy at the moment."
