*It took 17 years and a Las Vegas residency for Mariah Carey to return to the Billboard Music Awards, which takes place on May 17 in the same city.

Billboard and Dick Clark productions announced Tuesday that Carey – whose “Mariah #1 to Infinity” residency at the Colosseum at Caesars Palace begins Wednesday (May 6) – will appear on the annual awards show, but did not reveal which one of her record number of No. 1 Billboard Hot 100 hits she would be playing – if any.

The woman has more No. 1 songs on the Hot 100 chart than any other solo artist in the chart’s 56-year history.

Previously announced performers include Kelly Clarkson, Sam Smith, Ed Sheeran, Van Halen, Britney Spears and Iggy Azalea. Presenters include Rita Ora, Ne-Yo, Laverne Cox and the cast of “Entourage” — Kevin Connolly, Kevin Dillon, Jerry Ferrara and Adrian Grenier.
