Adam Lambert, Ariana Grande, Celine Dion To Perform On ‘Greatest Hits’ Finale

ABC’s summer series Greatest Hits wraps up for the season this Thursday, August 4, and we’ve scandalously not even tuned it once (save for that clip of Meghan Trainor performing “I Want It That Way” with Backstreet Boys). But it’s looking like the finale might just be the time to finally check it out, given the lineup of performers.

The last episode of the season is a two hour one that’s set to features Adam Lambert covering George Michael‘s “Faith,” Ariana Grande doing not one, but two Whitney Houston songs (“How Will I Know” and “Queen Of The Night”) and Celine Dion performing her Academy Award-winning Titanic theme song, “My Heart Will Go On” (albeit remotely, from Montreal).

Additionally, John Legend will tackle a pair of songs of Lauryn Hill‘s classic The Miseducation Of Lauryn Hill album, and — what a time to be alive, folks — Flo Rida will perform a “tribute to hip hop.”

Viewers overseas will also get much more of an eyeful of Adam Lambert (opposite Iggy Azalea and Guy Sebastian) once The X Factor Australia begins airing its eighth season, while here in the States we’ll be seeing him in the role of Eddie in Fox’s reboot of The Rocky Horror Picture Show this October.
