The filing arrived shortly after E! learned that the pair—who tied the knot in 2006 following one year of dating—had been separated since the beginning of the summer, despite Nicole not initially wanting to part ways. 

And while their decision to split may have been one-sided at first, the duo have since reached a mutual agreement when it comes to coparenting Sunday Rose and Faith Margaret, 14, going forward. 

Indeed, weeks before her divorce filing, Nicole and Keith both signed off on a permanent parenting plan, which proposed their kids spend 306 days a year with their mother as the “primary residential parent” and 59 days with their father, according to the docs obtained by E!.

And as for what Keith has been up to since news broke about the breakup? The country star kicked off his world tour at the beginning of the summer, with his next stop scheduled in Hershey, Pa., on Oct. 2. 

And though neither Keith nor Nicole have spoken publicly on their breakup, the musician did make an eyebrow-raising change to lyrics of his song “The Fighter,” which was inspired by his romance with the Babygirl star, while performing on stage last month. 

The song’s original lyrics go, “When they’re tryna get to you, baby I’ll be the fighter.”

However, Keith instead sang, per a video his touring guitarist Maggie Baugh shared to Instagram Sept. 27, “When they’re tryna get to you, Maggie, I’ll be your guitar player.”
