Miley Cyrus

Full story from Star Magazine:

Liam is so worried about Miley’s dramatic weight loss that he’s threatening to call off the wedding if she doesn’t gain weight — do you think this is a fair ultimatum?

Miley Cyrus better act fast. The 19-year-old’s fiance Liam Hemsworth is fed up with her extreme diet consisting of only 500 calories a day and working out for up to three hours every day.

“The ridiculous thing is, she started this regimen because she was worried Liam would fall for his [Hunger Games] co-star Jennifer Lawrence,” the source says. “She decided that the only way to keep him was to get the best body of her life.”
