Kim Kardashian's Engaged!

Another Kardashian is getting married and this time it's Kim's turn!

Her boyfriend of six months, New Jersey Nets forward Kris Humphries, was waiting in her bedroom on bended knee with four words written in red rose petals:

“WILL YOU MARRY ME?”

Kim says,

“I didn’t expect this at all,”

“I was in such shock. I never thought it would happen at home, and I never thought now.”

Humphries popped the question with a custom-designed, 20.5-carat Lorraine Schwartz diamond sparkler.

“I just knew I wanted it to be big,”

he said.

And boy was it big! Kim Kardashian's engagement ring is worth almost HALF as much as her Beverly Hills mansion ... sources say the rock is valued at $2 MILLION!!!!!!

The ring -- designed by Lorraine Schwartz -- features a 16.5 carat emerald cut center stone flanked by two 2-carat trapezoids ... for a grand total of 20.5 carats.

We're told the stones are all "the highest clarity and color."




..............hmm can't you just smell a new reality show cooking? ;)
