New York: Kanye West was very secretive about his proposal plans to Kim Kardashian, as he had managed to keep everything under the covers like a spy-op with cover stories and fake Instagramming.
One of the engagement party attendee, Joe Francis, told the New York Daily News that Kim Kardashian was even blindfolded for maximum drama.
The `Girls Gone Wild` founder said that the proposal was absolutely like a military operation, as the ruse was great real class act and the 33-year-old reality TV star was shocked and very happy.
The 40-year-old entrepreneur said that all the guests were contacted three or four days in advance and had sold the story that they were flying up to San Francisco to surprise Kardashian on her 33rd birthday.
He said that sisters Kourtney Kardashian and Khloe Kardashian said that they were at a spa in Arizona, and posted fake pics on Instragram.
Francis, who has been Kardashian`s friends for years, said that the TV star really believed everyone`s cover-up story and was absolutely shocked when they all came running onto the field at AT and T Park.
West, who pulled up in a car right in the middle of the field, and got down on one knee, with orchestra and fireworks in the background.
The 50 guests invited to the party hid in two dugouts, and ran out to join the couple after the proposal.
Francis added that the `Black Skinhead` hitmaker was a genius as he had managed to get all high-profile people to San Francisco, and moved them all around without anyone tweeting sightings.
