Wiz Khalifa is in mourning after his transgender sister died.

The 29-year-old rapper took to Twitter to pay tribute to his sibling Doren 'Lala' Thomaz, who passed away over the weekend at the age of 32.

He wrote: ''When you find someone who understands you and sets their personal needs aside to find out yours that's a beautiful thing.

''The loss of my sibling has been the hardest thing Ive had to deal with but wiith your prayers and well wishes my family will get though this (sic).''

Wiz - whose real name is Cameron Jibril Thomaz - and Doren's mother Peachie Wimbush also took to Instagram to share her daughter's obituary.

She included a quote from the movie 'Steel Magnolias' and wrote: ''...there was no noise, no tremble, just peace. 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.'' ---M'Lynn Steel Magnolias

''I have seen, heard and felt every bit of your love (sic).''

The obituary read: ''Dorien 'Lala' Thomaz, age 32, passed away peacefully with her Mother by her side on February 20, 2017.

''Lala was born on October 31, 1984 to Peachie and Laurence.

''Dear sibling of Cameron Thomaz and half sister Lauren Thomaz; also survived by grandparents, many aunts, uncles, and cousins (sic).''

The cause of death has not yet been revealed.
