21 Savage's younger half-brother Terrell Davis, who raps as TM1way, is dead at the age of 27.
According to reports, he was stabbed to death during an argument in London, England.
Savage mourned the loss on Instagram.
"I can’t believe somebody took you baby bro I know I took my anger out on you I wish I could take that sh*t back," Savage captioned a photo of the two.
TM1way and Savage share a father, Kevin Emmons.
Savage was notoriously exposed as a British citizen on Super Bowl Weekend in 2019.
