Rapper Dr. Dre's son has been found dead at his home.

Andre Young Jr., who was just 20 years old, returned from a night out at 5.30am on Saturday morning, but was discovered in his bed at 10am by his mother.

A cause of death has yet to be established, pending toxicology tests which could take 4-6 weeks.

A spokesperson for Dre, who is set to release his comeback album 'Detox' this November/December, said that the producer is "mourning the loss of his son. Please respect his family's grief and privacy at this time."
