Police were on Sunday morning investigating the death of 22-year-old Nelli Tembe, the fiancée of well-known musician AKA, at the five-star Pepperclub Hotel in central Cape Town.
AKA's publicist, Phumza Nohashe, said the Forbes and Tembe families would release a statement soon.
Witnesses at the scene described hearing a scream, followed by a “loud doef” sound, and said they had also heard a man shouting.
A source close to AKA said he was "inconsolable".
"Paramedics on scene have said a female had allegedly jumped from the 10th floor of that building. When paramedics arrived on scene, she had sustained polytraumatic injuries," Netcare 911 spokesperson Shawn Herbst said.
"She was in a critical condition and they started a full life-support resuscitation. Unfortunately her injuries were too severe and she was declared deceased," he added.
Pepperclub Hotel general manager Efi Ella also confirmed that a young woman had fallen from one of the upper floors of the hotel at 7.30am on Sunday.
