E! Online reports that Kanye, 36, rented out AT&T Park and proposed in front of the couple’s friends and family in an over-the-top ceremony on Kim’s 33rd birthday. Kanye got down on one knee and presented Kim with a 15-carat diamond ring by jeweler Lorraine Schwartz, while a 50-piece orchestra played Lana Del Rey’s “Young and Beautiful” and Keri Hilson, Ne-Yo, and Kanye’s “Knock You Down.”

A jumbo screen on the field flashed “PLEEEASE MARRY MEEE!!!” while fireworks lit up the night sky.

The stadium, home to the San Francisco Giants, was completely empty except for their closest family and friends, who poured out of the dugout and surprised Kim after she said yes.

Earlier in the evening, Kanye presented an award to Steve McQueen at the 17th Annual Hollywood Film Awards in L.A. before flying down up north for the surprise proposal.

Kim’s mother, Kris Jenner, was overjoyed. “A match made in heaven!” she told E! News. “I am so happy for both of my kids, Kim and Kanye.”

In December, Kanye revealed to fans at a concert in Atlantic City that he and Kim were expecting their first child together. The couple welcomed daughter North West in June.

“She’s my joy, and she brought my new joy into the world,” Kanye said of Kim during his appearance on Jenner’s talk show.

This will be the first marriage for Kanye and third for Kim, who was previously married to Kris Humphries and Damon Thomas.
