Engagement Details! Kanye's Crazy Romantic Proposal, Kim K's Gigantic Rock

Reality star Kim Kardashian and rapper beau Kanye West are engaged!

Once again, Kanye proved just how romantic he can be, with an over-the-top proposal that included a baseball stadium, orchestra and 15-carat diamond ring… on Kim's 33rd birthday.

West popped the question at AT&T Park in San Francisco, where the couple and friends and family were gathered to celebrate Kim's b-day.

A source tells "Extra" that Kanye blindfolded Kim before the big proposal. As “Pleeease Marry Meee” popped up on the jumbo screen and a 50-piece orchestra played Lana Del Rey's “Young and Beautiful” (they later played Keri Hilson, Ne-Yo and Kanye's “Knock You Down”), he got down on one knee and popped the question.

The entire family rushed out from the dugout to congratulate the couple as fireworks went off in the background.

The “Keeping Up with the Kardashians” star later posed for pictures with her new rock by celebrity designer Lorraine Schwartz.

Kanye added to the element of surprise by showing up in L.A. on Monday night as a presenter at the 2013 Hollywood Awards. He reportedly flew right back to San Francisco after the event to ask Kim to be his wife.

Kanye cleared the proposal with Kim's mom, Kris Jenner, and the momager couldn't be happier. “A match made in heaven,” Kris told E! News. “I am so happy for both of my kids, Kim and Kanye.”

Sister Kourtney posted the above stadium pic on Instagram with the caption, "She said YES!," while Khloé tweeted, “Tears of JOY!!!!!!! Wow!!!!!!”
