You know, Kim Kardashian may actually make a good wife after all.

First, she made the announcement that regardless of the fact that her maiden name is a brand that has made stars and fed a family, she is changing it to Humphries when she gets married.

Now, TMZ reports she’s convinced Kris Humphries and his lawyers to negotiate a prenup. What’s the “good wife” part, you ask? She’s got him convinced this prenup isn’t messing up HIS longterm dough.

Sources close to the couple tell us … both Kim and her NBA star hubby-to-be are telling friends, “It’s the smart thing to do.” And, by the way, they’re right.

We’re told the move isn’t one-sided. Both Kim and Kris have tons of loot. Kim is worth a reported $35 mil.

As for Kris … he’s not only making $3.2 mil a year with the Nets, his family also owns a couple of burger joints in Minnesota. Kris’ net worth is estimated at $8 million.

We’re told Kim’s late father, famed O.J. Simpson attorney Robert Kardashian, told her about the importance of contracts … and Kim feels her dad would have wanted her to take financial precautions.

Hell yeah, Kim needs to take precautions: he’d have to play ten years with the Nets while she just totally stops making money just to catch up. Cover your assests!
