The son of hip-hop star Dr. Dre has been found dead at his home in Woodland Hills, California, reports Reuters.

Andre Young Jr. was discovered "unresponsive in bed" by his mother on Saturday morning following a night out with friends. Paramedics pronounced the 20-year-old dead at the scene.

A statement from Dr. Dre's spokesman said: "Dr. Dre is mourning the loss of his son Andre Young Jr. Please respect his family's grief and privacy at this time."

The cause of death cannot be determined until results from toxicology tests are returned, which could take more than six weeks.

A Grammy-winning producer and artist, Dr. Dre will release his third album Detox this year. He has also produced records for Eminem, Snoop Dogg, 50 Cent and Jay-Z.
