Miranda Lambert looks positively regal in her first music video in more than a year. Donning a vintage dress and a riding coat that look to be from the 1920s, the country star visits the Cedars of Lebanon state park in Tennessee to let the wilderness bring to life the lyrics of her tearjerking new single, 'Over You.'

The official 'Over You' video won't be out until this Thursday (March 1), but The Boot has an early sneak peek. In this behind-the-scenes clip, Miranda's emotions run the gamut -- from choking back tears to smiling at a new friend who used to be in the circus! Watch it below.

Co-written with husband Blake Shelton, 'Over You' was inspired by the loss of Blake's older brother, Richie, who died in a car accident in 1991.

"I've never cried writing a song, and I don't know that I ever will again," says Miranda. "After we wrote it, Blake said he couldn't record this song for himself or sing it on stage every night but he would be honored for me to. 'Over You' is one of the most special songs I'll ever be a part of."

'Over You' is the second single from Miranda's chart-topping 'Four the Record' album. Come back to The Boot on Thursday for the song's official music video!
