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.

And let us not forget how good Grande is at impersonating her peers. Here's a look at the "Into You" singer doing impressions of Britney Spears, Rihanna and Celine Dion.
