Madonna – $800m
Over the years, Madonna has not failed to impress. The Queen of Pop has built up a huge fortune and now has three children: Rocco, David, and Lourdes. She has also gone into acting – remember The Next Best Thing back in 2000?
U2 – $838m
U2 has got to be one of the greatest band of all time. Nearly 40 years and $800 million after, the Irish band is still together and has gone on to make its mark on history. Larry Mullen Jr., Adam Clayton, the Edge, and Bono formed U2 in 1976. No doubt they have been through so many things together.
