Lindsay Lohan’s fragile frame has been a cause of concern for quite some time now, however photographs of the actress shopping in Los Angeles this week seem to have taken the term "scary skinny" to whole new level. Donning a low-cut strapless dress, the 22-year-old flashed a little skin … and a lot of bone.

According to Dr. Kent Holtorf, Director of the Holtorf Medical Group in Los Angeles (who does not treat Lohan) the 5’5'' starlet weighs around 95-100lbs with a Body Mass Index (BMI) of less than 16. But in order to be considered "healthy" she should be at least 113-149lbs with a BMI of 18-25.

"There are signs of muscle wastage, clearly her bones are protruding and she looks quite rigid," Holtorf told Tarts. "She looks like skin and bones at this point, Lindsay clearly looks malnourished and unhealthy for her frame."

"Lindsay texts Samantha non-stop, its crazy," said our source.

Lohan was spotted out at STK in Los Angeles over the weekend with her mom and sister, but according to eyewitnesses she was totally preoccupied texting her ex rather than indulging in food and conversation.

"Lindsay tells everybody she eats and is fine," added our insider. "But her friends and family are pretty worried."

Carrie Prejean Still in The Running For Miss Usa, Offered a Trump-like Lifestyle in NYC

Despite all the uproar surrounding Miss USA’s first runner-up Carrie Prejean, it must be noted that the controversial Miss California still has a shot at nabbing title in June. The pageant winner, Kristen Dalton, will go on to represent the United States at the Miss Universe pageant in the Bahamas and many believe she has a good chance of nabbing the title.

"The USA hasn’t won since 1997," explained an ex Miss USA judge who preferred to remain off-record. "But so far Kristen looks like she has what it takes - beauty, intelligence and a great personality. It may very well be our year."
