Fetty Wap's daughter died as a result of a health issue she'd carried with her since birth ... TMZ has learned.
The rapper and his ex Lisa Pembroke's 4-year-old, Lauren, died from a fatal cardiac arrhythmia due to complications of congenital cardiac anomalies ... this according to the death certificate. Essentially, that means she'd had this heart problem since birth, and the resulting irregular heartbeat killed her.
According to the document, obtained by TMZ, Lauren passed on June 24, 2021 ... at her home in Riverdale, Georgia.
Both Fetty and Lisa have posted touching tributes to their daughter during the last week ... which was the first time they'd definitively shared the heartbreaking news with the public.
Fetty seemed to imply Lauren had passed away a couple weeks ago -- during his set at Rolling Loud, he dedicated the performance to her.
He's got another child who came frighteningly close to death -- his daughter, Alaiya, underwent emergency brain surgery back in January 2019 ... a procedure that luckily went well.
