Dr Dre | House Tour 2020 | $ 40 Million Brentwood Mega Mansion

Dr. Dre may not have become "the first billionaire in hip-hop" as he promised in 2014, but he's still one of the richest men in the business. Forbes gave that title to Jay-Z, whose investments in Tidal and champagne brand Armand de Brignac raised him to billionaire status in June 2019.
