Soulja Boy is finally legal. The Atlanta-based rap star officially turned 21-years-old today (July 28).

Everyone from Nicki Minaj to Young Money president, Mack Maine (whose birthday is also today), made sure to send their well wishes to SB on his born day. Joking, Soulja sent a comment to Nicki on the social networking site, saying: “@NICKIMINAJ i'm 21 now. what it do? :p”

SB will be having a birthday bash in Miami that fans can watch live online at souljaboybirthdaybash.com.
