Demi Lovato

During a stop on Demi Lovato and Nick Jonas' Future Now Tour, Brad Paisley joined the pop stars to perform "Without a Fight" and "Stone Cold."

Brad Paisley has released his video for "Without a Fight" featuring Demi Lovato.

Demi Lovato hit the stage at the annual 'Christmas in Washington' special, and the adorable 'X Factor' judge brought her signature rock edge and powerhouse vocals to the table.

It seems that pop star Demi Lovato is considering going country. The ‘Skyscraper’ singer, who was perhaps best known for her roles in ‘Barney and Friends’ and Disney’s ‘Sonny With a Chance’ before taking on a music career, tweeted that she just wrote her first country song.
