Justin Bieber and South Korean sensation PSY are among the entertainers that have been added to the list of 40th Anniversary American Music Awards performers.

The newest acts were announcement Monday and also include The Wanted and Swizz Beatz featuring Chris Brown and Ludacris, Carly Rae Jepsen and Kelly Clarkson. The show's producers first announced a star-studded list last month comprised of Taylor Swift, No Doubt, Pitbull, Nicki Minaj and Christina Aguilera.

Bieber was in the spotlight over the weekend when word spread that he and long-time sweetheart Selena Gomez split. Though their busy schedules were blamed, rumors of a split surfaced early last month after the 18-year-old Bieber was seen spending time with Victoria's Secret model Barbara Palvin, 19.
