In an ultra-successful debut, Miranda Lambert's latest album, Platinum, landed at No. 1 on Billboard's country albums chart and the all-genre Billboard 200.

With her hard-earned superstar status propelling her to the top of the charts and media headlines, Lambert is admittedly learning day by day how to handle her level of fame.

"I wish there was like a handbook someone hands you when you start your career that has chapters so you can turn a page whenever you hit a new spot," she told CMT Hot 20 Countdown. "But there isn't, and it sort of comes out of nowhere sometimes. Things hit you out of nowhere at different times in your career and in your marriage, too. So it's something you have to get used to."

She and husband Blake Shelton try to take it all in stride.

"With Blake and I, all the things that have been going on with us and the tabloids and this new kind of level that we're at with all of this stuff going on, it just came out of nowhere a little bit," she said. "You kind of have to adjust to it a little bit."

Lambert says the effects of fame have stretched far beyond her own life and marriage and into the lives of others close to her. So when she found a song that resonated so close to her experience, it was an obvious choice for the new album.

"'Priscilla' just addresses it, and it does it in a smart way and in a fun way," she said. "I never could have written this song, but that's why I love it so much. I think it was written so well and really has a good perspective on what it's like."

It didn't take long for the track to find its way into the hands of Lisa Marie Presley -- Elvis Presley's daughter and an artist herself -- making an instant fan out of the singer and her mother, the song's namesake. They showed their love for the song with a photo on Instagram.

Lambert will kick off her Platinum tour on July 10 in Fort Loramie, Ohio, and continue on with dates across the U.S. through September.
