The 31-year-old Beyoncé has just kicked off her “Mrs. Carter” show tour, which began Monday night in Serbia and the pop diva is set to earn approximately $116 million from the world tour. She is also making millions as the new face of H&M's Spring Summer ad campaign.

Her husband, rapper Jay-Z has earned millions as co-owner of the 40/40 club, which has two locations in New York, and is reportedly selling his small share with the NBA Brooklyn Nets to extend his Roc Nation Sports representation business into basketball.

It comes to no surprise then that Jay-Z is contemplating to spend $4 million for a private island in the Bahamas for his family.
