'American Idol' hopeful Angie Miller was shockingly eliminated just before the finale this season, giving a tearful goodbye through song that even had us feeling things. However, she was able to return as originally scheduled to perform alongside our favorite alum, Adam Lambert.

The duo performed David Guetta's 'Titanium' together on the May 16 show, with Miller playing piano as she did during the season, and Lambert rocking his best instrument: the pipes.

They were perfect together, from their matchy-matchy black outfits (although we could have used more glitter) to their enormous smiles.

After singing together, Lambert introduced Miller's idol and muse Jessie J, whose songs she performed throughout the season. The pair sang Jessie J's song 'Domino' together -- you can see that video below.
