Mya on Beyonce's 'Lemonade': I'm Not Becky and I Never Have Been!

Mya's dodging the Beyhive by declaring she's never been a side chick to Jay Z -- but she's not exactly giving him a vote of confidence on the cheating rumors.

Our photog asked the singer if Beyonce's fans ever came after her the way they've been jumping on Rachel Roy. You'll recall Mya and Jay Z collaborated on "Best of Me (Part 2)" ... and there were rumors back then.

So check out Mya's denial, and especially listen for her closing comment about Jay ... and men in general.
