On Monday night, West rented out San Francisco's AT&T Park and took out all the stops for the proposal, which included a 50-piece orchestra and using the field's jumbo screen to flash "PLEEEEASE MARRY MEEE!"
The proposal was a big surprise for Kardashian, as it came just before Kardashian's 33rd birthday party, which she is throwing at Tao in Las Vegas on Friday.

After asking Kardashian's mother Kris Jenner for her blessing, West got down on one knee and proposed with a 15-carat diamond ring, with the orchestra playing Lana Del Rey's "Young and Beautiful" in the background.
Once Kardashian said yes, her family rushed out of the dugout to celebrate, to the pops of fireworks and Roman candles.
Sister Khloe Kardashian was the first to celebrate the engagement on Twitter.

West and Kardashian welcomed daughter North in June. No word yet on when the two will tie the knot.
The last time Kardashian was married -- to NBA player Kris Humphries -- it lasted just 72 days. Here's hoping Kimye makes it beyond that.
