Real Housewives of Beverly Hills

David Foster and Ariana Grande Perform “I Have Nothing” (VIDEO)

Ariana Grande’s vocals are often compared to Mariah Carey, but last week in Inglewood, California as part of her Honeymoon Tour, the pop star took on the legendary Whitney Houston in a show-stopping rendition of “I Have Nothing.”

Better yet? Grammy Award-winning musician David Foster — who co-wrote the mega-hit — came on-stage to accompany her on the piano. Let’s also not forget that David is the uber-supportive husband of Real Housewives of Beverly Hills star Yolanda Foster, too!

"I'm very, very excited. I'm very nervous," Ariana said as she introduced him to the crowd. "Because he is one of the most incredible songwriters of all time, and I can't believe I'm actually about to perform with him." Check it out:

Ariana called performing with David a “surreal experience,” and her vocal performance earned her screams of approval and roaring applause from the audience, especially as she hit those super high notes!

We bet that Yolanda was very proud of both her husband and Ariana. We’re also not-so-secretly hoping that Ariana makes an appearance or even a quick cameo on RHOBH in the very near future! Seeing the super sweet singer interact with the crazy Housewives would definitely make for some fabulous television, wouldn’t it?

The Real Housewives of Beverly Hills airs Tuesday nights on Bravo.
