Mika Brzezinski got into a heated debate with Matt Lauer over Miley Cyrus' VMA performance on Tuesday's "Today."


The MSNBC host — who has made no secret of her dislike for Cyrus' controversial performance — was a panelist on "Today's Professionals," and stressed that Cyrus' act was "disgusting and disturbing."


"There's pushing the envelope and there's porn, there's raunchy porn that's disgusting and disturbing and seeing... a 20 year old young woman literally in the process of her undoing and everyone clapping for it and being disturbed by it and talking about it and showing it, which I hope we don't," Brzezinski said. "Don't show it here on my segment, please."


Matt Lauer disagreed. "I think the only thing that surprises me is that we're surprised," he said, adding that she is a "paid performer" who was part of the year's "most provocative awards show" and performed during a "provocative" song. That set Brzezinski off.


After heated cross-talk, she protested, "Oversexualized is one thing. Is it sexual to stick your face in the face of a life-size teddy bear and stick your tongue out? We're talking about raunch, we're not talking about sexualization."


Lauer argued back, but Brzezinski told him, "Matt, no, we should denounce it."


Brzezinski railed against the performance at length on Monday's "Morning Joe."
