Kourtney Kardashian is the latest Hollywood starlet to fall victim to a home burglary.
Approximately $108,000 in jewelry was stolen Saturday from Kardashian's Calabasas, Calif. home, Los Angeles County Sheriff Sgt. Kristy Criner tells PEOPLE.
"That's what was discovered missing in the initial investigation," Sgt. Criner says. "Sheriff's investigators and our crime lab are responding on the scene."
A rep for Kardashian wasn't immediately available for comment.
Kardashian, 30, is expecting her first child with boyfriend Scott Disick around Christmas.
A rash of home burglaries have plagued young female stars in the last year: Paris Hilton
, Audrina Patridge
, Hayden Panettiere
, Lindsay Lohan
and Rachel Bilson
's homes have all been broken into within the last 10 months.
Last month, Nicholas Prugo, 18, was arrested
under suspicion of committing the break-ins at Patridge and Lohan's homes.
