co-founder Chad Hurley filmed Kanye West's over-the-top proposal to Kim Kardashian on Monday and posted the footage online.

The rapper popped the question on the reality star's 33rd birthday after renting out baseball stadium AT&T Park in San Francisco, Calif. Fifty of their friends and family watched from the dug-outs.

The two-and-a-half-minute video hit the internet on Wednesday and includes various clips from the evening's festivities.

At the beginning of the video, a string orchestra plays Lana Del Rey's "Young and Beautiful" as West gets down on one knee and Kardashian stands in the middle of the field in shock. He gives her a 15-carat diamond ring.

After she accepts his proposal, the crowd erupts in cheers and run out into the field to congratulate the pair.

The video also shows "Pleaseee Marry Meeee?" on the Jumbotron high above the gathering. At one point, the partygoers clink glasses of champagne to celebrate the event.

On the following night, during a concert for his "Yeezus" tour in San Francisco, West serenaded his fiancee. He told the crowd: "You know what song this is, right? I want to sing this song to the birthday girl that's back there right now, my fiancée."

The tune, "Bound 2," includes provocative lyrics that refer to Kardashian as a "good girl" and someone who is "worth a thousand bitches."
