Drew Barrymore and Will Kopelman are calling it quits.
The 41-year-old actress and her art consultant husband are separating after nearly four years of marriage, ET can confirm. The couple, who said "I do" on June 2, 2012, have two daughters together: 3-year-old Olive and 1-year-old Frankie.
Although no papers have been filed yet, a source tells ET talk of a separation has been going on since October 2015.

Page Six was first to report the news, which comes one day after Barrymore had her daughters' names tattooed on her wrist. "Getting a great little lifetime note on my arm," she captioned a photo of the new ink.
The couple was last spotted out together on Jan. 25, when they took Olive to the L.A. Farmers Market in Studio City, California. The week before, they attended the Plates for Pediatrics dinner for New York-Presbyterian Komansky Center for Children's Health together.
However, more recently, they have been spotted separately. Kopelman was all smiles when he was seen with Frankie at The Grove in L.A. on March 14, while Barrymore -- still wearing a band on her ring finger -- stepped out on Thursday to shop with a friend in Beverly Hills.

The duo celebrated their three-year anniversary last summer, at which time Barrymore posted on Instagram, "Happy anniversary Mr. Kopelman, cheers to you! I love you and I love our daughters !!!!!!! #threeyears"
This is the Charlie's Angels star's third marriage, following first husband Jeremy Thomas, which ended in 1994 after less than two months, and Tom Green, who Barrymore split from in 2001 after five months.
ET has reached out to Barrymore's rep for comment.

"It was never really love at first sight," Barrymore told InStyle last October of her husband. "Will struck a lot of my pragmatic sides. He was someone who was always reachable on the phone, someone who was a classy human being, someone who had this incredible blueprint of a family that I don't have."
"At the same time, what I love about him is that he embodies the power of choice," the actress added. "He chooses to be a good person every day."
