Last year, the unexpected news of divorce came from Reese Witherspoon and Ryan Phillippe; this year, another golden couple has announced impending separation: Sean Penn and Robin Wright Penn.

Actors Sean Penn and Robin Wright Penn married in 1996, after several years of dating. They have two children, son Hopper Jack, 14, and Dylan Frances, 16.

While their marriage appeared to be one of the most harmonious and perdurable, certainly by Hollywood standards, People magazine announced exclusively on its website Thursday that they are now divorcing.

The couple’s representative, Mara Buxbaum, confirmed the sad news exclusively to People. No other details were immediately available.

Penn, 47, and Wright, 41, have been private about their personal lives throughout these eleven years of marriage.

Penn was notoriously displeased with the intrusion of the press in his personal life during his marriage to pop music icon Madonna in the 1980s and has maintained a reticent attitude throughout the years.

The two actors have appeared together in movies, such as 1997's “She's So Lovely,” directed by Nick Cassavetes and 1998's “Hurlyburly,” directed by David Rabe.

Penn’s recent projects include “Into the Wild,” which he directed. It stars Emile Hirsch, Vince Vaughn, Jena Malone, Marcia Gay Harden and William Hurt. The film has received four SAG Award nominations and two Golden Globe nominations.

The Academy Award winner will next appear in the Harvey Milk biopic directed by Gus Van Sant for Focus Features. Filming reportedly starts in January, per Variety. Penn will portray gay rights activist Harvey Milk, who became the first openly gay politician in 1970s San Francisco.

Wright’s recent projects include this year’s “Hounddog,” starring Dakota Fanning, which she exec produced, and “Beowulf,” the animated film adaptation of the homonymous epic poem.
