Pregnant Kourtney Kardashian returned to her home in Calabassas, CA at 8:30 PM Saturday and discovered she was the latest celebrity burglary victim.

Kourtney had been in Las Vegas the night before celebrating sister Kim’s birthday.

Kourtney lives in a gated community in the L.A. suburb but that did nothing to stop the home invasion.

“$108,000 in jewelry was reported missing,” Los Angeles County Sheriff’s Department Sgt. Benning told RadarOnline.com.

An arrest was made last month in the burglary of Lindsay Lohan‘s home.
