The newly-engaged stars are suing YouTube co-founder Chad Hurly for secretly shooting a video of the event, which shows Kanye getting down on one knee and asking for his ladylove's hand while a 50-piece orchestra plays Lana Del Rey's "Young and Beautiful."
The footage then pans to a scoreboard illuminated with the message "Please marry meeee.”
The couple's lawsuit states Chad Hurley wasn't invited to elaborate proposal, but was allowed to stay because he signed an agreement saying he wouldn't post any video or images.
"Hurley proceeded to try to turn the event into one starring himself, broadcasting the images he knew were the exclusive property rights of someone else," reads the complaint.
Kanye allowed other cameras to film for E!, possibly to use the footage for Kim’s reality show Keeping Up With the Kardashians.
The 36-year-old rapper proposed to Kim on her 33rd birthday (Oct. 21) at San Francisco's AT&T Park, just a few months after the couple welcomed their first child, North, in June.
