Ariana Grande

Ariana Grande channeled Whitney Houston this week in Inglewood, Calif.

The 21-year-old pop star performed an emotional cover of the late singer's hit "I Have Nothing" in concert Wednesday. Grande was accompanied by the song's co-writer and producer, David Foster, on piano.

Houston recorded the single for The Bodyguard soundtrack. The 1992 film starred Kevin Costner as a former secret service agent hired to protect a celebrity singer (Houston), and earned $411 million at the box office.
