On Wednesday, CBS aired the Kennedy Center Honors ceremony, including acting Queen frontman Adam Lambert delivering an emotional cover of Cher’s 1998 mega-hit “Believe” that moved audience members to tears.

Towards the end of his rendition, cameras panned to Cher, who could be seen wiping tears from her eyes.

The 36-year-old performed “Believe” as a tribute to the Moonstruck actress, 72, who was a guest of honor at the services. The event also honored Reba McEntire, composer Philip Glass, saxophonist Wayne Shorter and the cast of Hamilton.

Lambert also joined Cyndi Lauper, 65, to sing “I’ve Got You Babe,” a Sonny Bono and Cher original.

Here’s how Twitter reacted to Lambert’s stunning tribute:

Is there a genre @adamlambert can't interpret or has one not been invented yet? #KennedyCenterHonors

.@adamlambert's incredible version of @Cher's "Believe" on #KennedyCenterHonors is proof that all of those of us who obsessed about him on American Idol can say, "We told you so." So there.
