Paula Patton has filed for divorce from estranged husband Robin Thicke, the Los Angeles Superior Court confirms to Us Weekly.

Patton and Thicke, who were high school sweethearts married for eight years, separated in Feb. 2014. At the time, a source close to the "Blurred Lines" singer told Us it had "been a long time coming" and that "their marriage was unraveling for a long time."

The split came after Thicke's controversial 2013 VMA performance with Miley Cyrus and after he was rumored to have cheated on Patton after pictures surfaced of him grabbing another woman's bare butt while posing for a photo.

According to TMZ, Patton cited irreconcilable differences and is seeking joint legal and physical custody of their 4-year-old son Julian. TMZ reports that the divorce is "harmonious."

Following their split, Thicke went to great lengths to try to win his wife back, going as far as to crying on stage at the BET Awards in June, where he told the crowd: "Good evening, my name is Robin Thicke, I'd like to dedicate this song to my wife, and said, 'I miss you, and I'm sorry.'" The lovesick singer then released an album in her honor titled Paula

In July, Thicke admitted he was at a loss when it came to winning Patton back. "I actually have no idea what I'm doing," he said on Good Morning America. "I'm just kinda flying by the seat of my pants on this one."
