UPDATE: Watch Usher assist on the new Michael Jackson single
The tweet also promised the performance would feature a "special guest," and odds are that it's Justin Timberlake, who posted to Instagram a photo of the single's cover art, which lists Jackson and himself as the song's artists.
If you can't wait until tonight, you can take a listen to Jackson's original demo of "Love Never Felt So Good," which was written in 1983 (Johnny Mathis recorded a version of the song in 1984). "Love Never Felt So Good" is one of eight cuts set to appear on Jackson's posthumous album, Xscape, which sees release on May 27th.
To compile the album, executive producer, L.A. Reid (who also serves as chairman and CEO of Epic Records) scoured four decades' worth of music in the Jackson estate vault, looking for songs with completed vocal tracks that he then handed off to a variety of producers to give them a "fresh, contemporary" sound. Timbaland acted as the album's lead producer, while other producers include Stargate, Jerome "Jroc" Harmon, John McClain and Rodney Jerkins (who worked on the original version of the title track, "Xscape," with Jackson). A deluxe edition of the album will also include the original versions of each song.
