The goggles should give you an insight into just how serious she took this.

Melissa McCarthy dropped by 'The Tonight Show with Jimmy Fallon' last night to, amongst other things, promote 'The Boss' and gift Fallon a 'Turtle-Tie Dickey', but most of her time probably went into prepping for her Lip Sync Battle which she absolutely destroyed.

Fallon gave it his all to Zayn's 'Pillowtalk' but was no match for McCarthy and her choice of 'Colours of the Wind' from Disney's 'Pocahontas', which she spared no expense on performing. Nice to know where all those comedy dollars are gone.

Now if you'll excuse us we have to listen to the 'Pocahontas' soundtrack in its entirety. Come, run the hidden pine trails of the forest with us...
