We Can't Stop singer Miley Cyrus may have started extreme dieting to help cope with alleged, and never ending, Liam Hemsworth relationship troubles, according to sources.

The 20-year-old faced alleged claims of a breakup and end to her engagement many times in the past few months, including rumors suggesting that Hemsworth, 23, was kissing actress January Jones back in February. With scarce details about their wedding plans, insiders also reportedly said they are working hard to keep their relationship strong and "balance it all" with their busy work schedules.

Insiders linked her healthy regiments to relationship issues with Hemsworth. Cyrus' friends now worry about the singer's health and constant dieting, saying she has taken to dieting mainly to help get past the romance troubles she faces.

"Her diet and exercise regime has become like a religion - it's what's getting her through one of the more stressful times of her life," an insider allegedly toldHeat magazine, quoted by Entertainmentwise. "But she can't carry on this way. People are scared she'll make herself ill."

Cyrus reportedly only eats raw vegetables and fruit, and egg-white omelettes, exercises two hours a day in the gym and runs five miles three times a week, according to the website. The former Disney Channel star started losing weight last year and has since been flaunted a more sexy and raunchy image, the sources added.

A source told HollywoodLife.com Cyrus' new ultra-sexy image has causes disputes between her and the Hunger Games: Catching Fire actor. One source said, "They've had a lot of fights about it" and Hemsworth feels disrespected by the way Cyrus has turned into a highly sexualized celebrity figure.

Cyrus made an appearance on Good Morning America on June 26 and confirmed her relationship status.

"I'm wearing a ring, so..." she said, suggesting that her engagement with Hemsworth is still on.
