Kim And Kanye's Lavish Proposal: 7 Things You Didn't Know

Kanye pulled off the 'surprise of a lifetime,' and it was all on camera.

For months we've been wondering just how Kanye West pulled off one of the most over-the-top proposals, and on Sunday (February 16), we finally got some answers.

On the latest episode of "Keeping Up With the Kardashians," we got a close look at Kanye getting down on one knee to propose to Kim with a 15-carat diamond at San Francisco's AT&T Park.

So what did we learn about the epic proposal that we didn't know before? Well, we've rounded up the seven things that went down behind-the-scenes at Kimye's engagement.

1. Kris Jenner Had It On Lock-Down

Only Kanye and Kris knew what was going on the night of October 21. Kris was in charge of getting Kim's family and friends to San Francisco without anyone finding out, which meant chartering a private jet, keeping social media on lock-down and making sure everyone kept quiet at the time of the proposal.

"I know first hand the real Kanye," Kris said during Sunday's episode. "He is a sweetheart with a huge heart for everyone that he loves. He's so many things that I don't think a lot of people get the chance to see."

2. Kim Was Sick

Turns out Kim, who left baby North at home for the festivities, really had no idea what was going on the night of the proposal. Only a few hours before Kanye popped the question, Kim told Khloe that she was under-the-weather and really "wanted a simple night sleeping in."

3. It Was A Fairytale Proposal

Khloe said it best when she said, "I didn't know this was real life," when watching the most magical proposal of all time. In a scene that felt like it was lifted out of a movie, Kanye and Kim watched as the 50-piece orchestra performed Lana Del Rey's "Young & Beautiful." During the performance Kanye got down on one knee, to the surprise of her family, and asked Kim if she would be his bride. "Of course" was her answer.

4. The Surprise Was On Kim

Many believed that Kim may have had a clue of what was going on, but if she did then she sure fooled us. Kim said during the episode that she credits herself as "the biggest investigator" and the fact that she didn't see the proposal coming, which left her shaking, was "the surprise of a lifetime."

"It feels like I'm in a dream," Kim said. "It's just the most amazing experience. I can't believe this is happening.

5. After The Proposal Was The Afterparty

Following the proposal, champagne was popped and dancing and speeches commenced. Kris congratulated the happy couple, while Khloe wished for more babies to join baby North, but Kanye said it best with a simple, "I love you" to his bride-to-be.

6. The Story Behind The Ring

Not only did Kanye's proposal to Kim take a lot of planning, it turns out the $1.25 million Lorraine Schwartz diamond ring did as well. Kanye was up all night deciding the mounting of the stone and that he actually preferred to get a smaller diamond because it would have been a flawless, but, not surprisingly, Kim loved it.

"It just really is the most beautiful thing I've ever seen," Kim said.

7. Bruce And Scott Weren't There

Many were wondering why Bruce Jenner and Kourtney's long-time boyfriend Scott Disick didn't attend the family event. Turns out Bruce was traveling, and Scott was home in Long Island after his mother suffered a seizure. Tragically, shortly afer his

mother died with his father passing only two months after.
