Aguilera, 35, announced she and Grande, 22, will perform on the reality competition's Season 10 finale in a tweet Monday. The episode will air Tuesday, May 24 at 8 p.m. ET.
"Excited to share the stage with @ArianaGrande on tomorrow night's @NBCTheVoice finale. #GirlPower #XtinasFinaleDuet," the "Dirrty" singer wrote.
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."
Aguilera's contestant, Alison Porter, is up against Laith Al-Saadi, Adam Wakefield and Hannah Huston in the finale. The "Genie in a Bottle" singer has served as a coach for six seasons, but has yet to have a contestant win the competition.
