After 13 years of non-wedded bliss, Tim Burton and Helena Bonham Carter have called it quits.

A rep for Bonham Carter confirms to Yahoo that the two "separated amicably earlier this year and have continued to be friends and co-parent their children." Their statement continues: "We would ask that you respect their privacy and that of their children during this time."

Burton, 56, and Carter, 48, met in 2001 when he directed her in the remake of Planet of the Apes. The two were never officially married, but do have two kids together: Billy Raymond, 11, and Nell, 7. The unconventional couple also never fully cohabitated; instead, the two lived in adjoining houses in London.

"They say Tim and I are a mad couple with subterranean tunnels between our adjoining houses, and that our children live down the road with another couple," Carter told the U.K.'s Radio Times in 2010 of their living situation. "We just have two houses knocked together because mine was too small. We see as much of each other as any couple, but our relationship is enhanced by knowing we have our personal space to retreat to. It's not enforced intimacy. It's chosen, which is quite flattering — if you can afford it."

Following their teaming up on Planet of the Apes, Burton and Carter frequently collaborated on films together such as Big Fish, Charlie and the Chocolate Factory, Sweeney Todd: The Demon Barber of Fleet Street, Alice in Wonderland, and Dark Shadows.

Though they split earlier in the year, the two clearly remain close. On Saturday, Nicole Scherzinger posted this picture on Instagram of Burton and Carter visiting her backstage after a performance of Cats.

Currently, Burton is promoting his latest film Big Eyes, the true story of the painter Margaret Keane starring Amy Adams and Christoph Waltz. This year, Carter was nominated for an Emmy for her portrayal of Elizabeth Taylor in Burton & Taylor. Next year she'll star alongside Meryl Streep in Suffragette and as the Fairy Godmother in a live-action version of Cinderella.
