In case there was ever any doubt, Ariana Grande reminded fans that she can really sing when she hit the Greatest Hits stage.
The 23-year-old pop star performed the late Whitney Houston's 1985 song, "How Will I Know," for the ABC show's season finale, and we haven't seen someone perform like this since, well, Houston herself!
After nailing "How Will I Know," Grande was joined by a group of male dancers on stage to perform "Queen of the Night," a song off the 1992 soundtrack for Houston's movie, The Bodyguard.
Grande is clearly a fan of the singer, as this isn't the first time she's covered her music. In March, she performed "I Will Always Love You" during a sketch on Saturday Night Live, and in 2014, she sang "I Have Nothing” for the Obamas at the White House.
