Miley Cyrus Midriff Baring TwitPic Raises Concerns

The 19-year-old starlet recently tweeted a belly-baring photo of herself with the caption, “my ‘Fiance’ jeans. but for real though.”

The photo raised much concern that the “Last Song” actress is losing too much weight, but her personal trainer Mari Windsor has defended her saying that “people need to chill out.”

Miss Windsor continued, “She's healthy and she feels good, that's the main thing. She's smart about her body. She wanted to sculpt her body, that's all.”

Back in April, Miley faced harsh criticism regarding her sudden weight loss and she was forced to defend herself, explaining it was due to allergies. Miss Cyrus explained to her critics, "For everyone calling me anorexic, I have a gluten and lactose allergy."

Despite the concern, the former Disney star appears to be healthy and happy.
