Where in the world is Matt Lauer?

Sexting the interns.

At least that is what Page Six says.

The Gossip column writes that Lauer is accused of sexting female staffers at NBC, allegedly sending lewd messages and revealing pictures to women including a young intern.

Sources tell Page Six that the reason he was fired so quickly by NBC News is that the messages, saved by an NBC employee whom he approached while they were in Sochi, Russia, for the 2014 Winter Olympics, “showed incontrovertible proof of inappropriate sexual behavior on his part.”

It is believed the first woman to come forward and complain about Lauer is a junior production worker who was at the 2014 Sochi Olympics as an intern, where she was first approached by Lauer.

NBC News President Andy Lack said in a meeting with staff Wednesday that Lauer’s involvement with the woman, who has not been named but is still an NBC employee, continued after they returned to New York.

A source told Page Six, “There’s at least one picture [sent to her by Matt] which was a major part of the evidence, which is why the firing came so quickly … my understanding was it was so damning that it was unquestionable whether or not he should be fired.

“I think everyone was a bit surprised how quickly this all turned around. No one expected his termination to happen that quickly. I believe the silver bullet was the photo and that was so damning that they had no other option but to fire him.

“Plus, the girl had a high-power attorney and so everyone knew if NBC didn’t make a decision and push it out quick, they would have arranged for a sit-down interview with a competitor [and the messages could be made public]. Matt took the news well once he realized he was in a corner. He was very apologetic.”

Lauer’s spokesperson declined to comment, as did his personal attorney when approached numerous times by Page Six. NBC reps also declined to comment on his alleged sexting.
