Miley Cyrus

Willie Nelson, Jimmy Fallon and Jimmie Allen are just a few of the collaborators joining the cast for Parton's new holiday musical film.

Even though they co-starred in a T-Mobile ad spot during the Super Bowl this year, Dolly and Miley still don't typically communicate over the phone.

From epic duets between Kelly Clarkson and her mother-in-law Reba McEntire to the decades-spanning career of the Judds, moms and daughters rule in country music.

Parton stars in the ad with her goddaughter, Cyrus.

Smith is releasing her version of this Miley Cyrus co-write.

There are many country music stars who have equally famous relatives, many of whom are in the music industry as well.

When you're a country star, you can celebrate Take Your Child to Work Day any day!

Morris and Cyrus are "Dancing Queens"!

Cyrus wished her legendary country godmother a happy Mother's Day during her performance.

Yep, Miley had to dust off her dad's old fax machine to get the invite from Dolly.
