As for why she's confirming, TMZ's Raquel connected the dots Tuesday ... making a compelling argument the former couple had to do somersaults to avoid each other in Miami over New Year's Eve. They partied separately and on top of that, they were apart on Xmas.
To quote Drake in "Back to Back, "I don't want to hear about this ever again. Not even when she tell him that they better as friends."
