According to the Blast, the actor filed the documents in court on Friday, three months after announcing their split.

"They still deeply love and respect each other and remain very close friends but have mutually decided to separate after being together for 20 years. They have a son together who they will continue to co-parent," Silverstone's representative said in a statement to People magazine.

Silverstone, 41, and the musician have one child together, six-year-old son, Bear Blu. The pair had been married since June 2005.
