What to do when you're bored? If you're Lindsay Lohan, you post topless tweets of yourself.

The actress gave her followers something to gawk at Monday when she uploaded a topless self-portrait onto her Twitter page. Technically, her long hair extensions strategically cover her assets — but it's still an eyeful.

"OLD PHOTOS," Lohan wrote. "I'm THAT bored."

The semi-nudes were taken in January during a photo shoot for Italian clothing label Fornarina, for which Lohan serves as the summer 2009 spokeswoman, according to Us Weekly.

What do you think of the photo? Titillating or a lame attempt at publicity?
