Brenda Song's Stolen Jewelry -- Jewel Thieves Are Party Buzz Kill


Brenda Song's jewelry became independent on July 4th ... because it looks like someone who attended a bash at her home made off without thousands of dollars in designer bling.

We're told the "Suite Life of Zack and Cody" actress threw a big party at her North Hollywood home ... and she didn't lock up some Chanel earrings, a ring and a bracelet.

She didn't notice someone made off with the jewelry until a few days after the party, and that's when she called the cops.

Sources tell us there's no sign of any break-in, so it does indeed look like an inside job. 

So for now, it appears a partygoer is $7,000 richer, and cops are on the case.
