After 20 years of marriage, actress Alicia Silverstone and her husband Chris Jarecki are getting divorced. Alicia, who is best known her role as Cher Horowitz in the classic teen movie Clueless, announced their split three months ago but the couple has been separated for considerably longer than three months.

Alicia, 41, filed paperwork in court on Friday, May 25, according to The Blast, and she listed their date of separation as March 15, 2016 which means they split up just before their 11th wedding anniversary. The reason for their divorce is listed as irreconciable differences and Alicia is asking for legal and physical joint custody of the couple's seven-year-old son Bear. Alicia and Chris, who is the former frontman of the rock band S.T.U.N., had a prenuptial agreement that will make things like spousal support and the splitting up of property easy because they already have an agreement in place.

The couple started dating in 1997 and they tied the knot in 2005 during a private ceremony in Lake Tahoe. Back in Feburary, Alicia's rep confirmed their split in a statement. "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," read the statement, obtained by E! News.

On the road to Hana. The feeling I have being with Bear on our adventure is so giddy…divine…so free and I feel so lucky to have carved out this time for us to just be. And being his mom, caring for him, is so sweet and lovely. Sand, rain, all of it. Beach walks at night, paddle boarding on the Hanalei River. The drive from Hanalei to Ke’e Beach-it has a wild and moody feeling. Anini Beach is so calm and nice to swim in with good vibes from the people hanging there. We stopped at the St. Regis for a quick look-the view there is so epic and beautiful…we met some lovely friends and decided to return the next night for some hot tub in the rain action ..chasing kids and hopping back and forth between tub and pools. The oceanside path that runs along the Coconut Coast. So pretty. All with my little man Bear. When he is tired at bedtime he is so insanely cute and has so many stories, thoughts and ideas. I want to savor these nights. I'm a naughty mommy for staying up late cozy in bed chatting and storying with him.

In the months since her split from Chris, Alicia has been focused on her career — she currently stars in the Paramount TV series American Woman — and she's also focused on being a mom to Bear. Back in March, Alicia gushed over spending time with her son during a vacation in Hawaii.

"On the road to Hana. The feeling I have being with Bear on our adventure is so giddy…divine…so free and I feel so lucky to have carved out this time for us to just be. And being his mom, caring for him, is so sweet and lovely," she wrote on Instagram. "When he is tired at bedtime he is so insanely cute and has so many stories, thoughts and ideas.
