Half of the New York hip-hop duo Mobb Deep, has died. Prodigy was 42.

The rapper's publicist said in a statement Tuesday that Prodigy was hospitalized a few days ago in Las Vegas "for complications caused by a sickle cell anemia crisis." Prodigy has battled sickle cell since birth and was in Las Vegas for a performance.

The exact cause of death was not clear, the representative said.

"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," the statement read. "We would like to thank everyone for respecting the family's privacy at this time."

Prodigy was born Albert Johnson in New York. He found success in the '90s with fellow rapper Havoc in Mobb Deep. The duo's hits included "Quiet Storm" with Lil Kim, "Shook Ones (Part II)" and "Hey Luv (Anything)."

Prodigy released a cookbook of prison recipes last year, based on his time in jail. The book, "commissary kitchen: my infamous prison cookbook," was released on Infamous, Prodigy's own imprint at Brooklyn-based Akashic Books.
