The mystery has finally been cracked!

Tiffany Haddish started a total frenzy when she confessed that an actress "on drugs" bit Beyonce during a backstage mix-and-mingle following one of Jay-Z's concerts, and people were practically foaming at the mouth trying to figure out who it was. Now, TMZ says for certain that it was none other than Sanaa Lathan!

The source said it was meant to be playful and not aggressive, but that it came after Queen B felt Sanaa was getting a little too close to comfort with her hubby and stepped in.

Lathan totally denies it, too!

"Y'all are funny. Under no circumstances did I bite Beyonce and if I did it would've have been a love bite," she tweeted as speculation reached a fever pitch.

Now we can all go back to living and breathing.
