"Dr Dre is mourning the loss of his son, Andre Young Jr," publicist Lori Earl said in a statement.

Mr Young Jr, who was named after his father, was found dead on Saturday by his mother at their home in suburban Woodland Hills, LA, the county coroner's office said.

A post-mortem has been performed, but the cause of death was not likely to be determined for eight weeks while toxicology tests are carried out.
