Kim Kardashian, Kanye West Sue YouTube Cofounder

Kim Kardashian and Kanye West may be paparazzi magnets but they prefer their private affairs off-camera. After the rapper proposed to his long-time reality star beau two weeks ago at AT&T Park in San Francisco, footage of the engagement somehow leaked onto the Internets.

In a lawsuit obtained by TMZ, prior speculations proved right as KimYe’s lawyer, Eric George, comes for YouTube co-founder Chad Hurley, who posted a clip of the proposal on his new Internet venture, MixBit.

They called Hurley desperate to find a “second act,” after two failed business ventures following his $1.65 billion YouTube sale to Google, and that he somehow manipulated his way into the event with no invitation. The couple only allowed him to stay after he signed a confidentiality agreement, along with a photo of him holding it.

KimYe adds, “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.”

While the high-profile twosome are suing for unspecified damages and don’t say how much the money’s worth, the footage was intended for MC Cable Television, an extension of Bunim/Murray and E!, which produces and broadcasts Keeping Up with the Kardashians.
