Of course!': Kim Kardashian gladly accepted Kanye West's proposal on Sunday's episode of Keeping Up With The Kardashians

As Kanye, 36, got down on one knee, Kim put her hands to her face in shock, and her sisters Khloe and Kendall Jenner gasped from their hiding place.

'You want to know what?' Kim asked coyly. 'If you’ll marry me,' Kanye responded, grinning from ear to ear.
After Kim whispered 'of course,' Kanye handed over a box containing a 15-carat diamond ring made by celebrity jeweller Lorraine Schwartz.

Out of the blue! Kim was completely shocked when Kanye dropped to his knees to pop the question

Extravagant: The setting had roman candles burning and a 50-piece orchestra playing

'I can’t believe this is happening,' Kim said as she kissed and embraced the father of her daughter, North, with the words 'Pleeease marry meee!!!' glowing on the stadium’s giant screen.

Kris was the only member of Kim’s family to know about the proposal in advance and had the tough task of getting the Kardashian clan to San Francisco and keeping it a secret.
The family matriarch had just four days to invite Kim’s closest friends and family members on the trip, telling them Kanye was throwing her daughter a birthday surprise.

The peanut gallery: Meanwhile, Kimye's friends and family all watched the proposal from the dugouts of the San Francisco Giants' baseball stadium

Big crew: Several people gathered at the stadium to support Kim and Kanye and were instructed not to use their phones or post on social media

As Kim’s sisters and brother Rob joined their mother on a private jet to San Francisco, they quizzed her about what was really going on.

But she remained tight-lipped under pressure, saying: 'I don’t know. I’m in the dark.'
A seemingly stressed Kylie Jenner told the cameras: 'My mom is making it so intense that we don’t ruin the surprise. This is so scary.'

No clues: Kim called herself 'the biggest investigator, so the fact hat she was completely shocked that Kanye proposed was 'the surprise of a lifetime'

What a rock! The reality TV star showed off her 15-carat sparkler

Careful! Even her sister Kendall Jenner joked that Kim would need a security guard for her ring

Disaster almost struck when Kim threatened to call off her trip to San Francisco, telling her family she was feeling sick and didn’t want to go.

But eventually she relented, unaware that her family and friends were dressed in black tie and being chauffeured to AT&T Park in buses.
When Kim’s sisters set foot inside the baseball stadium, they began to get suspicious that perhaps they weren’t just there for a birthday surprise.

She's in charge: Instead of putting the ring on Kim's finger, Kanye let her take the ring out of the box herself

Making the most of the venue: Even the sign in the stadium read 'Pleeease marry meee!!!'

'There’s no way it can just be a surprise for Kim. There’s something bigger,' Kendall Jenner said.

And when Khloe spotted jeweller Lorraine Schwartz she knew something was up.
'Lorraine lives in New York. There’s no way she would be here if it wasn’t something big,' she speculated.

Whoa! Kim's sisters Kendall and Khloe Kardashian were shocked as they watched the surprise proposal, but also extremely happy to be a part of the magical night

As Kim and Kanye were about to arrive, Kris herded all the family and friends into the stadium’s dugouts, with strict instructions to turn their phones off, keep quiet and not post anything on social media until they got the go ahead.

As Kim and Kanye drove into the stadium, with Kim blindfolded in the car, the orchestra took position and a hushed silence fell.
'I can’t breathe,' an emotional Khloe whispered. 'This is the best thing I’ve ever seen in my life. I’m gonna cry. I didn’t know this was real. This is a movie.'

Hush hush: Family and friends tried to keep their travel arrangements private as they headed to San Francisco for the unexpected evening

Denial: Kris tried to pretend like she had no idea what was going on with Kanye's big surprise

Kim and Kanye stood arm in arm as fireworks went off, roman candles burned and the orchestra played ‘Young and Beautiful’ by Lana Del Rey.

After a stunned Kim accepted the rapper’s marriage proposal, her friends and family ran onto the pitch to congratulate them.
'I was shaking,' Kim told them when quizzed about how she was feeling. 'I forgot what I said,' Kanye admitted when Kim’s sisters asked her how he had proposed.

All dolled up: Prior to the party, the Kardashian/Jenner girls pampered in a hotel suite, but Kendall borrowed one of Kim's necklaces without her knowing

Momager: Of course, Kim's mother Kris Jenner was in on the big surprise

Admiring her ring, which sparkled under the floodlights, Kim told her future husband: 'It’s, like, the perfect size for my hands.'

'I actually preferred to get a smaller stone that was flawless than some off the bigger offsets,' Kanye said.
The rapper also revealed that he had been up all night finishing the design of the ring and making sure it was perfect.

Even better: After sealing the deal, Kim and Kanye's friends ran into the field to greet the newly engaged couple
