Lindsay Lohan: Jewelry Thief?

Feb. 2, 2011— -- Life's not looking up for Lindsay Lohan.

Late Tuesday, the Los Angeles Police Department began investigating Lohan in connection with the possible theft of a $2,500 necklace from a jewelry store in the Venice area of Los Angeles.

As part of the investigation, LAPD detectives obtained a warrant to search Lohan's Venice residence, where she's been living since she left the Betty Ford Clinic in January.

Law enforcement sources told the Los Angeles Times that surveillance video shows Lohan wearing the necklace, which disappeared after she visited the store in January. After detectives started looking into the case and began preparing search warrant, a friend of Lohan's brought the necklace to the Pacific Division police station.

Representatives for Lohan did not immediately respond to ABCNews.com's requests for comment.

It's not the first time the 24-year-old starlet has been connected with missing gems. In 2009, British police investigated the disappearance of $400,000 worth of Dior jewels from a photo shoot Lohan did with Britain's Elle magazine. At the time, Elle released a statement exonerating Lohan, saying "Elle has no reason to believe that Lindsay Lohan was in any way responsible."

She's also been the victim of theft. Lohan was one of many celebrities whose homes were looted by the Hollywood "Bling Ring" in 2008 and 2009.

If Lohan ends up on the wrong side of the law this time around, the consequences could be dire. L.A. Superior Court Judge Elden S. Fox spared Lohan jail time in October after she tested positive for drugs and violated her 2007 DUI probation. At the time, he warned Lohan that she'd go to jail for six months if she broke any laws and violated her probation again. (She has been to jail three times in connection with the 2007 case.)
