Russell, 47, hanged himself in a private residence on L.A.'s Mulholland Drive, the LAPD confirmed to Us on Tuesday.

Over the weekend, according to the source, Taylor grew concerned when she had not heard from Russell (father to her daughter Kennedy, 3) for several days. Finally, at the urging of a pal, the reality star and her assistant went to the house to check in on Russell, where they made their heartbreaking discovery.

Taylor filed for divorce on July 15 from Russell, citing physical and verbal abuse.
