Kim Kardashian and her boyfriend of six months are engaged, reports People.com

According to the report when Kardahian walked into her Beverly Hills home, Humphries was waiting for her in the bedroom, down on one knee, with the words Will you marry me? written in red rose petals. The couple got engaged on May 18.

I didn't expect this at all, Kardashian told People. I was in such shock. I never thought it would happen at home, and I never thought now.

The ring is a custom-designed 20.5 carat Lorraine Schwartz diamond.

I just knew I wanted it to be big, Humphries said. Humphries also admitted to asking Kardashian's mother, Kris Jenner, for help with the ring.

Kris really didn't want a big celebration, but he had jokingly told my mom he'd be fine if there were mini-horses there, Kardahian said. Later that night at the party, my mom brought out two mini-horses, covered in glitter, for us! IT was hysterical.
