Kim took to Twitter to lament how much she was missing new boyfriend Kanye West

"What happened to the days when you could lock your bags! We need to get back to that. There's no sense of security and no trust!" she continued, adding, "Shame on you."

In addition to expressing her anger over her stolen personal items, Kim also took to Twitter to lament how much she was missing new boyfriend Kanye West, 34, after the two parted ways in France. "I miss him," she wrote and attached an Instragram photo of West at a concert.

While in Cannes, Kim and Kanye were spotted grabbing lunch on a yacht, enjoying a sweet ice cream treat, and posing together on the red carpet at the premiere of West's film/art installation, Cruel Summer. You can check out all the pictures of Kimye's romantic French rendezvous below!

After a week of glamorous galas and partying on yachts, Kim Kardashian had a bit of bad luck while traveling home from the Cannes International Film Festival.

When the reality starlet arrived at LAX, she apparently found that there were some items missing from her suitcases. "Very disappointed in British Airways for opening my luggage and taking some special items of mine! Some things are sentimental and not replaceable," Kardashian, 31, tweeted over the weekend.
