Dr. Dre's publicist has confirmed that the rapper's 20-year-old son has died.

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

Andre, was named after Dr. Dre, was found dead on Saturday by this mother at their Woodland Hills home.

"She found him unresponsive and called paramedics," Los Angeles County coroner's spokesman Ed Winter said.

The cause of death was unknown as of Monday, pending an autopsy. The cause of death wasn't likely to be determined for eight weeks following "gamut of tests, including toxicology," according to Winter.

Andre Young Jr. was the topic of many paternity and child support disputes between Dr. Dre and his estranged baby mama, Jenita Porter.
