"Truly an incredible day..." Michele said of the photos.
"At rehearsal now practicing w/ my band for my first live performance of my single! Which is happening very soon! #dreamcometrue," she tweeted.
Michele discussed her album in the December issue of ELLE, telling the mag that she'd dedicated the song "You're Mine" to her late boyfriend Cory Monteith.
"It makes me so happy, this song," she said. "It makes me think so much of Cory. It was ours. When I think if him, I play this."
