Taylor Swift is set to hit the stage at the Billboard Music Awards, it has been announced.
The US pop star will perform at the event in Las Vegas on May 19, as will Canadian chart sensation Justin Bieber.
Billboard announced that Bruno Mars and RnB singer Miguel will also take to the stage. Those acts are finalists for the milestone award, a new honour presented to an act who has achieved a landmark on the Billboard charts in the last year.
Other nominees include The Band Perry and Pitbull.
Nominations for other categories haven't been announced.
Prince will receive the icon award at the show, to air live from the MGM Grand Garden Arena.
Online voting is open for the milestone award and will be narrowed to three finalists later this month.
