During the Inglewood, California, leg of her Honeymoon Tour, Ariana Grande treated fans to a surprise guest and one truly epic version of a Whitney Houston classic.

Calling "I Have Nothing" – which originally appeared in Houston's 1992 film "The Bodyguard" – one of her "favorite songs of all time," Grande introduced the song's scribe David Foster to the stage. He proceeded to accompany Grande (who is oh-so-adorably flustered and nervous about the opportunity) on piano. And the result is nothing short of magic.

We know Ariana has a superhuman vocal range, but we still cannot get over the fact that she hits every single note so perfectly – and while sitting down. Perching oneself in a daintily cross-legged position is honestly much harder than it looks – but doing so live in a seemingly casual fashion whilst belting out notes that only 0.00000001% of the population could hit under the most ideal of circumstances? GODDESS.
