Taking to Twitter on Friday night, she wrote: "To the paps who chased me through the airport yelling "we need to know- did you bite Beyonce!?" A- I basically only leave home for work and ginger ale. B- No, you don't need to know. C- What the f**k do you think?

"But can someone explain to my mom why anyone THINKS I bit Beyonce? She seems mad and also weirdly doubtful of me... (sic)"

And the 31-year-old actress is still perplexed by the whole situation.

On Saturday morning, she added: "Woke up with this thought: having to deny biting anyone as an adult is its own special hell/not the reality I was hoping to inhabit (sic)"

Meanwhile, 38-year-old Tiffany recently revealed she would never expose the identity of the biter, as she has allegedly signed a non-disclosure agreement preventing her from saying anything.

Speaking in her Instagram Story while getting her hair done, she said: "NDAs are real, so I'm not saying s**t about nothing."

Previously, Chrissy Teigen admitted she thought she knew who the mystery person was because they were "the worst".

She Tweeted: "I cannot leave this planet without knowing who bit Beyonce in the face.

"I can only think of one person who would do this. but I cannot say. but she....is the worst. (sic)"

But the 'Lip Sync Battle' star - who is married to musician John Legend - subsequently revealed that her original guess about the culprit was proven to be wrong.

She confessed: "My initial guess was wrong. The real person? I *never* would have guessed. I'VE SAID TOO MUCH (sic)"
