Regnegotiating the exiting pre nuptial agreement in light of revelations that the richer spouse has been caught cheating with a number of hostess skanks.
The pre-nup was only good for $20 million in the event of divorce. However, once her husband was caught cheating with a number of women, she is asking her lawyer to draw up a re-nup and renegotiate how much she will get for staying in the marriage, and how much MORE she will get int the event of divorce.
