Julianne & Derek Hough charmed the audience with their flaming 'Great Balls of Fire' dance

The crowd erupted in applause during the dancing pair's recent performance.

Siblings Julianne and Derek Hough wowed their fans during a recent performance on the stage of Dancing With The Stars, as shared by Country Music Family.

Dressed in piano-themed outfits, the talented siblings set the dance floor on fire as they grooved to Jerry Lee Lewis' Great Balls of Fire.

Their performance started with Derek descending a sparkling staircase toward the piano occupying the center of the dance floor.

The audience roared in excitement when his sister, Julianne, popped right out of the piano. They danced on the top of the piano and all over the dance floor.

Jaws dropped when Derek tossed Julianne into the air in a series of shocking moves.

Derek slid off the top of the piano onto Julianne's awaiting shoulders. She carried him across the dance floor.

This performance was part of the dance reality show's Design-A-Dance competition. This part of the contest allowed viewers and audience members to vote on the performers, song choice, dance style, and costumes for the performance.

This proved to be one of the most-loved performances of the Hough siblings.

Derek and Julianne have been dancing professionally for at least a decade. They have gone on tour across the United States.

Apart from being a dancer, Julianne is also a professional singer.

In May 2007, she released her first country music single, Will You Dance With Me, to raise money for the American Red Cross.

She later signed with Universal Music group Nashville's Mercury Nashville Division and released a self-titled album under this label. She also joined Brad Paisley's tour in 2008.

Julianne is also an actress, appearing in the 2001 hit film, Harry Potter and the Sorcerer's Stone, in an uncredited role.

She also appeared in the 2010 musical, Burlesque, starring Cher and Christina Aguilera.
