Alicia Keys: ~ $14.9 Million, New Jersey
Alicia Keys has one of the most amazing voices in the music scene today, and her career has truly blessed her financially over the years. She once owned a massive mansion in New Jersey, which has a total of 32 rooms. The mansion features an interior that has a very modern and artsy vibe to it. It also has an indoor pool that has a glass roof. Keys, who in 2019 hosted the annual Grammy Awards, decided to put the mansion on the market back in 2015 with an asking price of $14.9 million.
