Kim, 30, says she was in "shock" when she walked into her Beverly Hills home to find boyfriend Kris on bended knee with a custom-made 20.5 carat Lorraine Schwartz engagement ring with the words "will you marry me?" spelled out in red rose petals.
Kardashian tells People she didn't "expect [it] at all," and especially not in her home.
The two have only been dating since December, but it seems the future newlyweds have the Kardashian klan's full blessing, with Kim's mother Kris Jenner helping to plan a celebration following Kim's acceptance of the proposal.
No word yet on a date for the wedding. This will be Kim's 2nd marriage.
