The cardinal rule in any celebrity marriage is that you must must must get a prenup--and Beyonce and Jay-Z are no different.
According to Ryan's KISS FM morning show, if the couple splits, Beyonce will get $10 million dollars for the first 2 years of marriage and $1 million a year after that for 15 years. She'll also get a $10 million dollar house if they split.
Not too shabby! But Beyonce has her own mullah so she really doesn't have anything to worry about.
