Is Lindsay Gaining Weight?

Nope, doesn't look like it! But she is back to wrapping scarves around her head... maybe she's embarrassed by the bleached blonde locks?

The young starlet shopped - what else? - at American Apparel in Hollywood yesterday before chucking a soda can at the paps later that night. Hmm, wonder what happened in between to make her so angry! Mood swings are the WORST.
