Seeing as one of Emma Stone's appearances on 'The Tonight Show' was its most watched videos of all time, it's safe to say that Jimmy Fallon was only delighted to have her back on the show.

In fact, we're pretty sure that we can blame Stone for the success of 'Lip Sync Battle', but we won't hold it against her.

Last night, Stone took part in Fallon's 'Whisper Challenge' game but with a twist inspired by her appearance in the upcoming musical film 'La La Land' and instead she and Fallon had to decipher songs from a muted performance by the other.

Seeing as it took nearly three minutes for her to play one single round, we doubt it's a game that the show will be repeating.
