The country star's ideal team up would be with the 'Single Ladies' star, as she's blown away by her vocal abilities.
When asked about her dream duet, she replied: ''Beyonce! I've seen her in concert five times.''
However, for her new record, 'Platinum', the 'Automatic' singer was very happy to sing with fellow country beauty Carrie Underwood on 'Something Bad'.
She explained: ''I sent her a rambling email asking her to do it. I figured she'd think I was crazy, but she wrote straight back saying she was in.
''I was so nervous the day she ended up coming to the studio. We ended up having a blast.''
The 30-year-old singer - who recently lost 25lbs in three months - also sings about putting on weight in the track 'Gravity's A Bitch', but says she wrote the track to stay ahead of the game.
She added to Us Weekly magazine: ''My fans expect me to lay it all out! I've always been happy with myself. But when I hit 30 I thought, it's not getting easier. So I chose to get ahead of it. There's still nothing I love more than a bag of Cheetos though.''
She's swapped the studio for a film set with new Netflix series.
