Emaciated Macaulay Culkin: What happened to the 'Home Alone' star?

macauley-culkin-thin-gi.jpg Macaulay Culkin appears to be wasting away to nothing. In a new set of photographs, the one-time "Home Alone" child star looks to have lost a load of weight, leaving him gaunt and hollow-eyed.

While Culkin, 31, is a lanky guy anyway, the photos -- taken on the street in New York and posted by U.K. newspaper The Sun -- reveal a scarily thin face covered in scruff.

We're hoping it's for his rumored upcoming role in "Service Man," described on IMDB.com as, "an uplifting military action comedy drama, made in the style of the 1980's feel good movies."

In 2004, Culkin was arrested in Florida for possession of marijuana and two controlled substances. He later pleaded guilty to all charges. He also testified at Michael Jackson's 2005 child molestation trial, saying he had slept in the singer's bedroom multiple times as a child, but that nothing "untoward" had happened.

In 2008, his sister Dakota was killed when she was struck by a car in Los Angeles.

Culkin appears above in 2006 and, in the inset, in 2012.

UPDATE: A publicist tells TV Guide that Culkin is "in perfectly good health" despite speculation floating around on the Web. She also adds that he's not a member of the "Service Man" cast.
