Kanye West and Kim Kardashian were all smiles after their engagement.

Kim and Kanye have been double-krossed.

A new MixBit video shot by YouTube co-founder Chad Hurley shows the exact moment rapper Kanye West proposed to Kim Kardashian on bended knee inside San Francisco's AT&T Park on Monday night.

The footage starts from a vantage point more than a hundred yards away and shows Kardashian and West standing side by side on the rented baseball field watching fireworks dramatically illuminate the darkness behind a 50-member orchestra.

It later jumps to West down on one knee in the fully lit stadium. There's no audio of his actual proposal, but the video shows Kardashian lean forward with her hands covering her face in apparent surprise.

Kardashian, 33, then takes a slight step toward the rapper while he apparently keeps talking and the orchestra keeps playing. The giant jumbotron with the message 'PLEEEASE MARRY MEEE!!!' is just out of sight.

The 'Keeping Up with the Kardashians' star moves closer yet again, and West, 33, stands to embrace her as a crowd of family and friends hiding in the dugouts starts cheering and running toward the newly betrothed couple.

Kardashian reaches out and hugs her sister Kourtney first, the video shows.

Other edits show the post-proposal celebration with caterers passing out drinks and revelers hugging and snapping photos.

It ends inside an unidentified location with momager Kris Jenner giving a toast while Will Smith's 15-year-old son Jaden Smith stands beside Kardashian's younger sister Kylie Jenner, 16.

'So, congratulations,' Kris Jenner says as daughter Khloe Kardashian, 29, reaches out and clinks glasses with West.

'Happy Birthday,' the 57-year-old matriarch continues. 'What an incredible birthday present, and I'm thrilled Kanye is in your life, and vice versa.'

The handheld video also captures footage of professional camera crews hard at work recording the big event.

It's not yet clear if and how the couple will share the intimate evening with TV viewers.

One partygoer who spoke to the Daily News said the proposal was planned like a secret spy-op, so it's almost certain the video leak was not sanctioned.

'It was absolutely like a military operation. The ruse was so great, a real class act,' attendee Joe Francis told The News Tuesday.

The 'Girls Gone Wild' founder said all the guests were contacted just a few days before and told they were flying up to San Francisco for Kardashian's surprise 33rd birthday party.

Francis said Kardashian's sisters Khloe and Kourtney went the extra mile to cover their tracks.

'I think Kim thought her sisters were abandoning her. They said they were in a spa in Arizona,' he said. 'Kim really believed everyone was where said they said they were. Her face was just absolute shock when we all came out running.'

According to Francis, about 50 guests hid in two dugouts as Kardashian and West drove onto the field.

'They pulled up in a car right in the middle of the field, around second base,' he said. 'She was blindfolded, and there was crowd noise over the speakers, so when she got out of the car, it probably sounded like it was packed with people. The sound came from all around, it was really cool.'

He said Kardashian looked 'stunning.'

'She was so beautiful, and people gasped when he got down on one knee. We were about 200 yards away, so we were watching this play out like a long shot in a movie,' he said. 'Everybody got choked up. It was so dramatic with the orchestra and the fireworks.'

He said when everyone ran out to join the couple, he made a beeline for his friend.

'The first question I asked her was, 'Did you say yes?' Then I asked Kanye, 'Did she say yes?' There was this big question on the billboard and we needed an answer. She just looked at me and said 'YES!'' he recalled.

'It was just adorable, one of the most romantic things I've witnessed,' he said.

Other guests included Hurley and Zynga founder Mark Pincus, he said.

'I believe Kanye is a genius, I do,' Francis said. 'He got all these high profile people to San Francisco, to hotels and moved them all around without anyone tweeting sightings. We were all sworn to radio silence.'
