A hip-hop legend is dead at the age of 49.

MF Doom, who was born as Daniel Dumile, "transitioned" on October 31, according to his wife Jasmine.

However, she only disclosed this to his fans on New Year's Eve over his Instagram feed.

"The greatest husband, father, teacher, student, business partner, lover and friend I could ever ask for," she stated in a heartfelt message. "Thank you for all the things you have shown, taught and given to me, our children and our family.

"Thank you for teaching me how to forgive beings and give another chance, not to be so quick to judge and write off," she continued. "Thank you for showing how not to be afraid to love and be the best person I could ever be. My world will never be the same without you. Words will never express what you and Malachi mean to me, I love both and adore you always. May THE ALL continue to bless you, our family and the planet."

The British-born producer was known for his elaborate lyrics and always appeared with a mask at his shows.

This was inspired by Doctor Victor Von Doom supervillain in Marvel Comics.

Some might wonder if the death was a stunt, given MF Doom's proclivity for playing tricks.

But Rolling Stone has confirmed through his management that he is indeed dead.
