There's more ... TMZ can confirm
reporting by
B. Scott, who said the drama appears to have stemmed from Chris'
scrapped AMAs performance last year -- when he was set to do an MJ tribute, only to claim he got the rug pulled out from under him last minute.
Our sources say that is, indeed, true -- and the reason he went after Teyana here is because we're told she was actually involved in the planning of that performance ... but something went awry before the day of. This makes sense, as it's been widely reported of late that TT has stepped into the role of a creative director lately for a number of artists/their shows.
Anyway, Chris clearly felt some type of way, and was confronting her -- which only escalated when she snubbed him. Not just that, but we're told Chris actually demanded Usher make her leave ... in addition to asking her to get out himself, seeing how it was his bday party.
We're told Usher refused, and the rest is history ... some of which you can
see on video.
Time will tell, we suppose, if Chris will come out himself, or if he'll address this further. BTW, it looks like Teyana -- who was once a fierce CB defender -- has unfollowed him on IG.
