FIRST LOOK: Yeezus! New Video Reveals Kimye's Bended Knee Proposal With Full Orchestra & Fireworks

Kanye West got down on one knee when he proposed to Kim Kardashian – and it has all been caught on tape, RadarOnline.com is reporting.

Chad Hurley, the co-founder of YouTube, filmed a behind-the-scenes video of Kanye’s proposal to Kim at the AT&T Park in San Francisco on her 33rd birthday, Oct. 21.

In the clip, a 50-piece orchestra is playing Lana Del Ray’s “Young and Beautiful” before Kanye, in a dark suit, bends down on one knee and proposes to Kim, in a short white dress, with the 15-carat Lorraine Schwartz diamond stunner.

After Kim says "yes," Kanye gets up and the pair hug.

Her friends and family including sisters Khloe and Kourtney Kardashian are then seen rushing onto the field to join the pair as “PLEEEASE MARRY MEEE!!!” flashes on the jumbotron.

Later, Kim and Kanye pose for pictures and both sing and dance along to his hit song “All of the Lights.”

The video ends with a toast from an unidentified woman: “Congratulations. Happy birthday. What an incredible birthday present. I’m thrilled Kanye is in your life and vice versa.”
