Kim Kardashian is calling it "the worst moment in my life."

Last night, five armed gunmen dressed as police officers barged into the Paris apartment she was renting and stole a ring worth $4.5 million and a jewelry box containing other items worth $5.6 million. It's unclear if the jewelry belonged to Kardashian or if they were loaners for Paris Fashion Week.

Kim was bound and gagged during the ordeal. She reportedly begged for her life, telling the invaders that she had kids at home.

Upon hearing about the incident, Kanye West abruptly cancelled his show at the Meadows Festival in New York City mid-set and rushed to the airport to meet his wife, who returned home right after speaking to police.

Kardashian's regular bodyguard Pascal Duvier had accompanied Kim to Paris, but wasn't in her apartment during the robbery. Instead, he was out with Kourtney Kardashian and Kendall Jenner.

Paris police believe the robbery could be an inside job, as the thieves probably knew security at the tony apartment complex would be light on a Sunday night.

But the Kardashians don't seem to think Duvier had anything to do with it; he was with the family when Kim arrived back in NYC.
