MTO WORLD EXCLUSIVE: We've Got Some TEA . . . On the Matt Lauer Sexual Harassment Claims . . . And The Woman WHO MADE THEM!!!

Original: just got some EXPLOSIVE TEA. Word at NBC is that the woman claiming that Matt sexually harassed is a former Today Show co-host.

We're also told that she plans to GO PUBLIC as soon as the end of the week.

NBC didn't want the smoke, so they fired him.

The network announced earlier today that Matt - who's been with the series for 20 YEARS - had been terminated from the show, effective immediately.
