Hurley filmed a behind-the-scenes video of West's over-the-top proposal to Kim on her 33rd birthday, Oct. 21.
In the clip, a 50-piece orchestra is playing Lana Del Ray's “Young and Beautiful” before the rapper, in a dark suit, bends down on one knee and proposes to the reality TV star, in a short white dress, with a 15-carat Lorraine Schwartz diamond stunner.
But Kardashian was seeing red after the video appeared online, because in the lawsuit, she alleges that Hurley signed a confidentiality agreement.
The docs state, "Hurley proceeded to try to turn the event into one starring himself broadcasting the images he knew were the property rights of someone else."
The irony is that cameras for Keeping Up With The Kardashians were present and filming the entire proposal, which will air, although West will have the final approval of it.
Kardashian is seeking unspecified damages.
