Rocker Chris Robinson filed for divorce from Kate Hudson on Friday, citing irreconcilable differences. The 39-year-old frontman for the Black Crowes has been married to the 27-year-old actress for nearly six years. They announced their separation in August.
According to the Superior Court filing, Robinson is seeking shared custody of the couple's son, Ryder Russell Robinson, who will turn 3 in January.
Hudson, daughter of Goldie Hawn, was nominated for a supporting-actress Oscar for her role as rock groupie Penny Lane in 2000's "Almost Famous." Other screen credits include "You, Me and Dupree" and "How to Lose a Guy in 10 Days."
A call to Hudson representative Brad Cafarelli for comment after business hours Friday was not immediately returned.
Robinson's band formed in 1990 and released its first CD, "Shake Your Money Maker," that year.
Its hits include "Hard to Handle" and "She Talks to Angels."
