Single Lindsay Lohan spotted looking painfully skinny

Lindsay Lohan was spotted looking painfully skinny, just days after her traumatic split from DJ Samantha Ronson.

The Mean Girls actress revealed her stick-thin arms and a protruding rib cage while she went shopping with her kid sis Ali in Los Angeles.

Lohan later tried covering up her skinny frame under a baggy shirt while she went for a party.

This is not the first time Lindsay has been spotted looking ultra-thin. Back in 2005 she had acquired the same tiny frame, when she acknowledged to Vanity Fair magazine that her weight had gone out of control.

"I knew I had a problem and I couldn't admit it. My arms were disgusting. I had no arms," The New York Daily News quoted Lindsay, as telling Vanity Fair in 2006.

Lohan recently told Us Weekly that she feels "so alone" after her early April split from Ronson, her girlfriend of a year.

"I'm a f--king 22-year-old girl who's in love," she said.

"I'm just really hurt. This whole situation is sick," she added.
