Waka Flocka Flame is mourning his younger brother Kayo Redd, an aspiring Atlanta rapper who died on Sunday.

Waka's mother and high-profile hip-hop manager Deb Antney confirmed the sad news on Twitter late Saturday evening, telling fans, "I just lost another son."

Earlier in the day Waka simply tweeted, "God please bless me" but a few hours later he followed up with a slideshow of his younger brother, writing, "Ya Big Brother love you Kayo."

Antney previously revealed that she lost a son in a car accident when Waka was 13 years old.

Few details have emerged about the cause of Kayo Redd's death, with mixed reports pointing at suicide or a possible shooting. Redd's final tweets were promoting his latest mixtape Red Kisses, which he dropped this summer. Before that, he released the YNS 2: Full Time Grind mixtape in 2012.

It's been a difficult ride for Waka, who also lost his fellow Brick Squad rapper Slim Dunkin in an Atlanta studio shooting in 2011.

Nicki Minaj, who was previously managed by Deb Antney, reached out to share her condolences via Instagram, writing, "Devastated by the loss of this precious soul... Always so sweet to me... I cant even... Sending prayers and all my love to Deb, Waka, Wooh, Quam, Big Joe, Bimmy, the entire fam... Gone too soon Kayo... Gone way too soon."
