Oh no! Miley’s figure is looking SUPER frail! One expert estimates she’s down to almost 105 pounds! Do YOU think she looks too thin?

Miley Cyrus‘ pilates work-outs — mixed with a gluten-free diet — may be putting her health in serious danger.

The 19-year-old stepped out in Miami looking scary skinny in a grey dress that hung off her tiny frame. Her legs looked stick thin, her collarbones popped and her waist looked noticeably smaller.

“Miley looks to be 108 pounds. She definitely appears to be losing muscle mass at this point,” Alicia Hunter, weight expert and author of The Accidental Diet: From Fugly to Fox, told .

As previously reported, Miley shed an estimated 25 pounds in two months: 135 pounds in February to 110 pounds in April. Now that she appears to be drastically thinner, she has lost an estimated 30 pounds in less than three months.

“To appear this undernourished this rapidly is not a good sign! For her to continue to drop weight would be inadvisable. She’s probably consuming less than 1000 calories per day,” Alicia tells us. ”I think Miley is taking her extreme weight loss to a new low. Her collarbone area is extremely bony and in the most recent pictures, her hip bones are protruding.”
