'Suite Life' Star Brenda Song 4th of July Jewelry Heist Victim

Brenda Song Stolen Jewelry
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.
