The Band Perry will take to the stage for a performance during the 2015 Miss Universe competition.

The sibling trio, along with Charlie Puth, have been named as performers for the event, set to take place on Sunday night (Dec. 20). Singer-songwriter Seal will host the competition, which will air live from Planet Hollywood Resort & Casino in Las Vegas, Nev., beginning at 7PM ET on Fox.

TBP are not the only country act to appear at such an event in 2015: Brett Eldredge was among the judges for this year's Miss America competition, which took place in September.

The Band Perry were also on TV earlier this month, performing at the 2015 Rockefeller Center Christmas tree lighting extravaganza. There, they sang "Santa Claus Is Comin' to Town," but at Miss Universe, they'll likely be performing their newest single, "Live Forever." The song comes from their upcoming album, Heart + Beat.

“This album, we’re dreaming in color,” Kimberly Perry explains. “Everything is so colorful and enthusiastic and happy. We’re walking out of the studio with giant smiles on our faces.”

A release date for Heart + Beat has not yet been announced.
