Nicky Hilton is Scary Skinny (Photos)

is a model, socialite and fashion designer. The super skinny 24 year old is the second oldest ofand's four children and sister to. She has had one failed marriage, which was annulled in 2004 after less than two months.

Nicky was seen yesterday leaving a medical clinic in Beverly Hills. It has been rumored that she is being treated for an eating disorder. We don't know if there is a smattering of truth but the photos taken on Tuesday attest to her very thin upper legs and arms. Keep in mind, cameras generally add the appearance of 10-20 extra pounds. That being the case, she is decidedly underweight.

Check out the pics from yesterday as well as some that were taken recently. It looks like Nicky is losing muscle mass. The closeup of her legs show that she is becoming bowlegged - not attractive.
