It's official: Robin Thicke did not "Get Her Back."

On Wednesday (October 8), news broke that Paula Patton had filed for divorce from the "Blurred Lines" singer after nine years of marriage. E! News has since confirmed the story.

The actress cited "irreconcilable differences" as her grounds for divorce, but sources tell TMZ that the split is "harmonious."

Paula, 38, has requested that she and Robin, 37, share joint physical and legal custody of their only child, Julian Fuego Thicke. He is 4 years old.

Thicke and Patton first announced their separation back in February of this year. Newly obtained court documents from the divorce proceedings provide the exact date as February 21.

"We will always love each other and be best friends," they said in a joint statement released at the time of their separation. "However, we have mutually decided to separate at this time."

Within months, the singer had launched a public campaign to patch things up with his wife, debuting the new song "Get Her Back" with an emotional performance at the 2014 Billboard Music Awards. His subsequent seventh studio album, Paula, was released in July to lackluster sales.
