Diamond Blue Smith (born August 13, 1984), known by his aliases Baby Blue, Baby Blue Whoaaaa and Bigg Money Blue, is a rapper, songwriter and producer from Miami, Florida.

He embarked on his music career in 1997 as a member of the group Pretty Ricky, which rose to popularity the following decade with their debut single “Grind With Me” and their first two albums Bluestars (2005) and Late Night Special (2007) before experiencing a decline following the departure of singer Pleasure P.

Baby Blue stepped up to sharing his own solo music in the 2010s, first with a remix of Tory Lanez' “Slow Grind” in 2017 and then with his own original track “Bedroom.” He also ventured into TV as a recurring cast member on the reality show Love & Hip-Hop: Miami for its first two seasons between 2018-2019.

The next decade would see him getting shot while in the parking lot of a bowling alley, arrested and sentenced for his involvement in a PPP loan scheme during the COVID-19 pandemic, and revamping himself as Bigg Money Blue after his early release from prison.
