Miley Cyrus, Lorde and Jennifer Hudson will perform Saturday night at the Beverly Hilton Hotel, according to the Associated Press, which added that Davis is promising a surprise appearance by "a music legend."
Lorde, the 17-year-old New Zealand singer and songwriter behind the smash hit "Royals," is nominated for four Grammy Awards at Sunday's ceremony, including song of the year and record of the year.
A deadpan indictment of pop-star consumption run amok, "Royals" topped Billboard's Hot 100 last year for nine straight weeks, sandwiched between repeat visits to No. 1 by Cyrus' "Wrecking Ball."
Despite the success of the latter tune -- and its nudity-enhanced music video -- Cyrus was shut out of the 2014 Grammys (though Dr. Luke earned a nod as producer of the year thanks in part to his work on "Wrecking Ball").
