The Band Perry (“If I Die Young”) added some twang to classic Queen rock song "Fat Bottomed Girls" for billboard.com's weekly Mashup Mondays series. And you can see the results here.

“We’ve always stood at the crossroads of country music and rock ’n’ roll which is why we chose a Queen cover," Kimberly Perry explains.

The offering is part of billboard.com's series that takes artists out of their genres for a song. Grace Potter, who sings "You and Tequila" with Kenny Chesney, covers the Beyoncé hit “Why Don’t You Love Me” for that same series.

Kimberly also says she loved Queen lead singer Freddie Mercury, who died just eight years before Kimberly was born.

“Freddie is my most favorite entertainer of all time. He's so real but at the same time, he's so dramatic,” she says.

“And I think it's a really fine line to be relatable to your audience, but also you have that rock star presence. And Freddie was all of those things.”
