The hip-hop world is again mourning the loss of one of their own.

Prodigy, one half of the iconic hip-hop duo Mobb Deep, has passed away.

The 42-year-old Queens native died Tuesday in Las Vegas, where he was performing with the Art of Rap tour along side fellow hip-hop artists Ghostface Killah, Onyx, KRS-One, and Ice-T.

“It is with extreme sadness and disbelief that we confirm the death of our dear friend Albert Johnson, better known to millions of fans as Prodigy of legendary NY rap duo Mobb Deep,” his rep said in a statement. “Prodigy was hospitalized a few days ago in Vegas after a Mobb Deep performance for complications caused by a sickle cell anemia crisis.”

The statement continued, “As most of his fans know, Prodigy battled the disease since birth. The exact causes of death have yet to be determined. We would like to thank everyone for respecting the family’s privacy at this time.”

Our thoughts and prayers are with Prodigy’s friends and family.
