Wiz Khalifa is mourning the death of his sister, Dorien “Lala” Thomaz, who died on Monday. Lala, who was transgender, was 32.
The rapper, 29, tweeted about his loss on Friday, writing, “The loss of my sibling has been the hardest thing I’ve had to deal with but [with] your prayers and well wishes my family will get through this.”
Khalifa’s mother, Peachie Wimbush, posted her daughter’s obituary on her Instagram page, including a quote from the film Steel Magnolias.
“…there was no noise, no tremble, just peace,” the caption read. “Oh God(dess), I realized as a woman how lucky I am. I was there when that wonderful creature drifted into my life and I was there when she drifted out. It was the most precious moment of my life.”
Four days before announcing her daughter’s death, Wimbush posted a photo on Instagram of herself holding another woman’s hand, writing, “Your prayers are necessary… thank you in advance.”
On Tuesday, Khalifa celebrated the 4th birthday of his son, Sebastian Taylor, whom he shares with Amber Rose.
Dorien’s obituary said she died “peacefully with her Mother by her side.” A cause of death has not been released.
