Kim and Kanye are engaged! (See the ring)

Kanye West and Kim Kardashian are engaged!

He did the asking in grand fashion, reports E! News. (Would you expect anything less?)

On Monday, on Kim's 33rd birthday, in front of friends and family, Kanye flashed "PLEEEASE MARRY MEEE!!!" up on the big screen at AT&T Park in San Francisco, reports Us Weekly.

He got down on one knee and proposed with a 15-carat diamond ring by celebrity jeweler Lorraine Schwartz. A 50-piece orchestra played Lana Del Rey's Young and Beautiful, followed by Keri Hilson, Ne-Yo and Kanye's Knock You Down, reports E!.

Kim's hairstylist Clyde Haygood was on hand to snap and share a pic of Kim flashing her new bling. "Guess what just happened!! #kimye."

Sister Khloe seemed to be weighing in on Twitter as she wrote: "Wow!!!!! Am I dreaming??!?!" and followed it with: "Tears of JOY!!!!!!! Wow!!!!!!"

And finally, Kim shared her own hand photo on Instagram.

As for how much it might be worth? "This is a classic, stunning ring and a beautiful choice for Kanye to present Kim with. It is hard to see from the photo, but it looks as though the diamond is either an emerald or a cushion cut, and knowing Kanye's taste, it is top quality," Brian Watkins, president of Ritani jewelry designers tells USA TODAY. "This type of ring could range anywhere from $4 to $5 million dollars."

In June, Kim and Kanye welcomed baby daughter North.

In the February issue of Cosmopolitan Kim said, "[Marriage] is something I know that we both want in our future, but I don't have this sense of urgency about it."

This will be the third marriage for Kardashian, who filed for divorce from basketball star Kris Humphries in 2011 after just 72 days as husband and wife.
