"When we got engaged I made sure the show was there (filming) because I felt like that's something that would make her happy. Regardless of how it was shot, I felt like this is a moment she would like to have and would like to share, and just have that documented. And we could decide later or not if we wanted to air it." Kanye West reveals why he chose to film his elaborate proposal to Kim Kardashian. The couple became engaged last month (Oct13).
