We can’t possibly know what hides behind Lindsay Lohan’s increasingly skinny frame, but if we were to trust her words, it’s because of the stress caused by the hard work she’s been doing lately.

Hollywood is one tough place to live in. While some celebrities are criticized for gaining a few pounds, see Jessica Simpson’s recent weight gain scandal, some get scrutinized for dropping too many and setting the wrong example.

Resembling more and more to a bobblehead doll, Lindsay Lohan showed off her slimmed down body in a low-cut dress and Christian Louboutin heels at the launch party of Matthew Williamson’s New York store on Sunday night.

Admitting the obvious, Lindsay said she did indeed lose some weight but defended her small frame saying it was “unintentional” and she is not suffering from any eating disorder.

Claiming to be eating just as she always has, Lohan cited the Big Mac she had at McDonald's recently as evidence. She reasons that the weight loss is a side product of working too much, stress, and lack of sleep when traveling.

“I think it's all that stuff that adds up,” the starlet said.

She refused to say how many pounds she melted over the past year, or last several months claiming she never weighs herself, but that Hollywood’s pressure to be thin is not her concern at the moment.

“They've already said everything about me that they can say. And I've never really cared then. I'm my own person, and people can say whatever they want. I'm still going to be the person that I am. And I think that's so important for people in Hollywood,” Lindsay said.

“You should always accept yourself for who you are. And that's what I've done, and I'm happy,” she added.

Lohan and her girlfriend Samantha Ronson just pulled out the last minute of a Valentine’s Day party they were scheduled to host on Saturday, claiming they were suffering from an ear infection. The night before, the two were spotted having a very public fight following Charlotte Ronson’s fashion show.
