Kim Kardashian\'s estranged husband, Kris Humphries, is demanding $7 million to sign off on their divorce, sources told TMZ.com. Other sources told the celebrity Web site the Kardashian camp quickly rejected the demand on the grounds the couple wasn\'t married long enough for Humphries to warrant $7 million in community property. Kardashian and Humphries split up just 72 days after their high-profile television wedding. TMZ\'s sources said the $7 million was sought to avoid a potentially embarrassing public divorce trial. Sources close to Kardashian contend Humphries actually made money on the marriage. The New Jersey Nets player got a cut of his efforts on the Kardashian reality series, including $1 million from the wedding special.
