Kimora tired of Russell?

US Weekly reports that Kimora Lee Simmons, 30, is ready to leave hubby Russell, 48, now that she has her own cash deposit.

A source said, "It just isn't working for her anymore. She is running a company and making her own money. The wife Russell wants is not the kind of wife she wants to be."

Russell said, "It's the same noise we hear all the time. All families struggle."
