BEYONCÉ is such music royalty, that it's hard to imagine anyone laying a hand on her without her approval . . . and the approval of an army of handlers. But apparently, that's not the case.
TIFFANY HADDISH says she met Beyoncé at a party last December, and she saw something crazy happen. She says there was an actress there . . . who she wouldn't name . . . who BIT Beyoncé "in the face."
And not in a playful way. Apparently, the actress was on something. Beyoncé wasn't really hurt, but she was mad.
Tiffany says Beyoncé ran off . . . got JAY-Z . . . and then they went into a back room. Tiffany says she had a couple run-ins with the actress that night and almost, quote, "beat her ass" after the woman told her to stop dancing.
Later that night, Tiffany and Beyoncé were together at the bar. She said, quote, "I said to Beyoncé, 'Did she really bite you?' She was like, 'Yeah.' I was like, 'She gonna get her ass beat tonight.'
"Beyoncé was like, 'Tiffany, no. Don't do that . . . she's not even drunk. The [B-word] is on drugs. She's not like that all the time. Just chill.'"
The Internet is already trying to guess WHO the mystery actress was, and so far, the names Sanaa Lathan and Sara Foster have come up. But they've both denied it.
Sanaa said, quote, "Under no circumstances did I bite Beyoncé, and if I did it would've been a love bite."
And Sara said, quote, "Flattering that anyone thinks I could get this close to Beyoncé."
