Alicia Silverstone met rock musician Christopher Jarecki outside a movie theater in 1997 when she was still at the height of her post-Clueless fame, and the couple had been together ever since, officially tying the knot in 2005. Silverstone's representatives now confirm to Page Six that the pair have separated.

“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,” the rep told the gossip column.

Jarecki was a member of the Geffen Records-signed rock band S.T.U.N., though the band has not been active since 2003. More recently he's played in the band The Bathroom Murderers, and has hosted a radio show. Jarecki also had a small part as a legal clerk in Silverstone's 2012 film Vamps, which also represented her reunion with Clueless director Amy Heckerling. Both Jarecki and Silverstone are vegans and animal activists; the family had adopted multiple rescue dogs together.

The couple has one son together, six-year-old Bear Blue. According to her Instagram, Silverstone was vacationing with her son in Hawaii when the news broke.

Silverstone is in the midst of something of a career resurgance as of late. She appeared in the arthouse thriller The Killing of a Sacred Deer with Nicole Kidman and Colin Farrell and received rave reviews for her brief but memorable work. She also has a role in Book Club, the upcoming movie which finds Jane Fonda, Diane Keaton, and Candice Bergen reading Fifty Shades of Grey. More prominently, she'll star in Paramount Network's American Woman, an upcoming scripted series based on the real life upbringing of Real Housewives cast member (and Paris Hilton's aunt) Kyle Richards, which means, essentially, she'll be playing Paris Hilton's grandmother.
