Lindsay Lohan Posts Topless Photo

Lindsay Lohan, who has recently vowed to get serious about her acting, sent out a semi-nude picture of herself on Twitter on Monday.

In the photo, taken on her Blackberry during a shoot for Italian clothing label Fornarina in January, long, blonde hair extensions strategically cover her chest. Lohan is Fornarina's summer 2009 spokeswoman, the Daily News reports.

Accompanying the photo she tweeted: "OLD PHOTOS…I'm THAT bored."

Lohan also tagged E! correspondent Ben Lyons and gossip blogger Perez Hilton in the photo's caption.

According to the Chicago Tribune, this latest attempt at self-exploitation isn't the first time Lohan's name has appeared in headlines in recent days.

The actress's tumultuous relationship with DJ Samantha Ronson was also in the news. Sources say that the couple's on-again off-again relationship is over for good this time because of Lohan's tendency to start "acting like a maniac."

And yesterday, the San Jose Mercury News reported that the actress is under suspicion for the theft of $400,000 worth of diamonds taken from a London photo shoot a few weeks ago.
