Listen up, Lindsay Lohan. I know Marilyn Monroe is your idol and all, and she did say "Diamonds are a girl's best friend," but hijacking high-end jewelry is not what she had in mind!

RadarOnline.com reports that cops have asked a Los Angeles judge for a search warrant for the starlet's Venice Beach home. They suspect that Lohan has stolen a piece of jewelry, and investigators told the court they have a video of Lohan wearing the missing jewels.

"Lindsay is being accused of stealing high-end jewelry, including a necklace," one law enforcement source told Radar. "A search warrant was requested Tuesday at the Airport Court to search Lindsay's house for the item of jewelry in question."

If this jewelry is valued at $5,000 or more, the troubled 24-year-old could be charged with a felony. She's still on probation after allegations from a Betty Ford clinic worker who claimed Lohan assaulted her, so any trouble with the law could land her back in court.
