Kim Kardashian and Kris Humphries signed prenuptial agreement
The newly engaged couple - who plan to marry later this summer - reportedly enlisted the help of Kim`s mother Kris Jenner to thrash out a deal to protect each of their earnings should their marriage fail.
A source told US Weekly: "Kim`s Beverly Hills home and all of her assets are protected. Additionally, she keeps anything she earns during the marriage."
Kim pocketed $10 million last year from her various endorsement deals and reality TV shows while basketball player Kris earns $3.2 million a year with the New Jersey Nets although his income is set to soar this summer when he becomes a free agent and can sign to a team of his choice.
Friends revealed the agreement is simply a precaution for the couple and say 26-year-old Kris is happy to sign to make his 30-year-old fiancee happy.
The source added: "He does not receive anything if the marriage fails. He agreed to that. He`s not worried."
Kim and Kris reportedly want to marry within the next two months although Kim is hoping her big day will rival the recent British royal wedding.
A friend revealed: "The wedding will happen within six to eight weeks. They`re doing things very, very quickly. It`s being fast-tracked.
"Kim is planning the wedding of the century. She doesn`t see why a royal wedding should get more attention that hers. She sees herself as a bigger celebrity than Kate Middleton."
