Justin Bieber forgets Spanish lyrics to 'Despacito,' ad libs nonsense instead

Whoever handed a mic to Justin Bieber at New York's 1Oak on Tuesday night should consider what he hath wrought.

First, the internet found footage of Bieber trying his hand at an ill-advised remix of Kendrick Lamar's latest single, "HUMBLE."

Now TMZ has footage of Bieber forgetting the Spanish lyrics to his guest spot on a remix of Luis Fonsi and Daddy Yankee's single "Despacito." But rather than declining to perform the song, Bieber plowed ahead, replacing the Spanish lyrics with..."bahbahbahbahbah."

He also hung out with the Chainsmokers, which makes perfect sense to us.

Somebody come get Bieber.
