Watch Ariana Grande Absolutely Slay Whitney Houston's 'I Have Nothing'

If this doesn't give you goosebumps, check your pulse.

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.
