Christina Aguilera and Ariana Grande will duet on season finale of "The Voice" tonight.
"Excited to share the stage with @ArianaGrande on tomorrow night's @NBCTheVoice finale. #GirlPower #XtinasFinaleDuet," the "Dirrty" singer wrote.
Grande, who impersonated Aguilera on "The Tonight Show Starring Jimmy Fallon" in September, responded by re-tweeting the star's post.
"Beyond excited and honored!" she added.
Aguilera was slated to perform with a hologram of Whitney Houston, but the late singer's estate nixed the project last week.Houston's executor, Pat Houston, told "Entertainment Tonight" the hologram was "not ready to air."
"Holograms are new technology that take time to perfect, and we believe with artists of this iconic caliber, it must be perfect," Houston's sister-in-law explained. "We have much respect and appreciation for Christina, and she was absolutely flawless."
The "Genie in a Bottle" singer has served as a coach for six seasons, but has yet to have a contestant win the competition.
Aguilera and fellow Season 10 coach Pharrell Williams will not return for Season 11 of "The Voice" this fall.
Miley Cyrus and Alicia Keys will serve as coaches with Adam Levine and Blake Shelton.
