Video of Kim Kardashian and Kanye West's engagement has arrived online. In the 2-minute MixBit clip, which was taken by YouTube co-founder Chad Hurley, the rapper can be seen proposing to the "Keeping Up with the Kardashians" star who turned 33 that day.

The video shows situation inside San Francisco's AT&T Park on Monday night, October 21. A 50-piece orchestra was playing songs in the dimly-lighted arena after fireworks exploded. Later, Kanye can be seen getting down on his knee. Kim covered her face with her hands with apparent surprise. The couple also shared a kiss and hug.

Family members and friends, who were watching the romantic scene from afar, can be heard cheering and laughing. They raced to the ground to congratulate the couple for their engagement. The guests had fun on the field, sipping drinks. Some men can be seen running around the field.

A guest at the proposal, Joe Francis, told New York Daily News on Tuesday that the people were contacted for Kim's surprise birthday party only a few days prior to the occasion. "I think Kim thought her sisters were abandoning her. They said they were in a spa in Arizona. Kim really believed everyone was where they said they were. Her face was just absolute shock when we all came out running," he recalled. About 50 guests hid in two dugouts when Kanye took blindfolded Kim to the middle of the field.

"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. Everybody got choked up. It was so dramatic with the orchestra and the fireworks," he added.
