3. Like Birdman, Master P was selling hundreds of thousands of records on his own before he signed any major record contract. Music mogul Master P was once one of the world’s highest paid emcees, reportedly worth a whopping $600 million. But now it seems the rapper has joined the ranks of celebrities and met with some financial backlash. After Master P was sued by a group of crew members from his 2003 film, Uncle P, for $240,000 in unpaid wages his net worth stands today at $350 million making him the third richest rapper alive.
