Kim K and Kanye West have agreed to keep their assets separate by drawing up a prenuptial before they walk down the aisle.  TMZ report that the couple are not signing the prenup because they’re worried that the relationship might fall apart but are doing so because “they're both business people and know given their vast wealth it's just the smart thing to do to have a prenup.” According to the celebrity news site Kim understands the importance of the agreement because her father repeatedly told her about the necessity of having very clear contracts when it came to wealth. However, sources have told TMZ that though the couple will keep their assets separate they’ll have a joint account for living expenses. At the moment there are reports that Kim’s wealth is valued at $40 million and Kanye’s at $90 million, though there are questions as to whether Kim’s actually worth more than her fiancé. Kanye currently ranks at no. 59 on Forbes’ Celebrity 100 list and Kim is at no. 66. With the engagement confirmed and a wedding on the way sometime in the future, Kim should see a spike in earnings if she continues to go down the reality TV route which let's face it, is more-than-likely going to happen. “We're told Kim's actually worth more than Kanye” say TMZ.
