Country spitfire Miranda Lambert wrapped her On Fire Tour over the weekend in Pelham, Alabama, finishing a crazy year of road work, during which she performed to more than a million people. To help commemorate a successful tour, fellow country star Patty Loveless joined Lambert on stage Friday night (Oct. 5) in Atlanta.

There, the two big-named country stars sang a duet of 'Dear Diamond,' a track Loveless also helped record for Lambert's 'Four the Record' album. Then, for the big sendoff, Lambert was joined onstage by tourmates Lee Brice and Brett Eldredge -- plus her Pistol Annies bandmates and Loveless again -- for a crowd-raising rendition of 'King of the Road.'

After the fact, Lambert thanked her fans for a good run via Twitter, posting, "Home. I made it. Been on the road since Jan. Thx to every person who came to see a show this year. It means the world! See ya in 2013!:)"

But just because her tour has ended, that doesn't mean the country star is going to be sitting around with her feet up the rest of the year. She is scheduled to perform at the upcoming CMA Awards, where she is also nominated for Album of the Year, Female Vocalist and Song of the Year for 'Over You, which she wrote with husband Blake Shelton.

Lambert also received nominations this week from the American Music Awards for Favorite Female Artist Country, as well as the American Country Awards for Artist of the Year: Female, Single of the Year: Female, Touring Artist of the Year, and Music Video of the Year: Female. Her latest single, 'Fastest Girl in Town,' is currently hot on the charts.
