A shocked Diana Ross doesn’t want to be stand-by mom to the Jacko Brood, sources say.

A very surprised Diana Ross was shocked when she was named in Michael Jackson‘s will as back up guardian to the late singer’s 3 children, Prince, Paris and Blanket in the event of his mother Katherine‘s death, Fox News reported.

While the former Supremes star and the late entertainer share a very special relationship dating back 40 years to when Motown prexy Berry Gordy anointed her as “official discoverer of the Jackson Five” it appears the diva wants no part of Wacko’s offspring.

According to FoxNews.com, Diana’s son Evan Ross, 20 and his GF were chatting about the Jacko will at Diddy’s Fourth of July shindig in Los Angeles presented by Starbuck’s ice cream.

Sources told Fox that the couple told pals Diana had no idea she was named secondary caregiver and wasn’t too thrilled about being saddled with the responsibility seemingly out of nowhere.
