Miranda Lambert's musician boyfriend Evan Felker has finalised his divorce.

The Turnpike Troubadours folk singer filed papers to end his marriage to Staci Nelson in February (18), weeks before it emerged he had already moved on with country star Lambert.

In May (18), Evan urged the judge overseeing his case to issue a scheduling order, ensuring there were no hold-ups in the court proceedings, and now the divorce is a done deal, according to Us Weekly magazine.

Evan and Staci wed in September, 2016. He apparently grew close to Miranda earlier this year (18), around the time of her split from fellow country musician Anderson East, while his band supported the Vice hitmaker on her Livin' Like Hippies Tour.

Lambert recently addressed gossip questioning when she actually started dating Felker, amid speculation of infidelity.

Indicating the tabloid rumours were unfounded, she insisted that if fans want to know the truth about her life, they should listen to her music.

"With social media, it's a whole other thing, and it's such bulls**t," she told website HITS Daily Double in June (18). "I'm thankful for the drama of it all because it gets sillier and sillier."

"They make up so many lies, no one can know the truth," she added. "The truth is it's in my music if you listen close enough. I took three months off all socials in 2015. I loved it. I realised I wasn't picking up my phone looking at Twitter and Instagram. I wrote 75 songs in six months because I wasn't using my mind staring at mindless s**t. I took a week off a little while ago, and it felt so good."

Miranda had previously started dating Anderson in 2015, shortly after her divorce from Blake Shelton.
