He might have been unfaithful, but nobody expected him to be a predator.

Matt Lauer's firing has caught everyone from his co-workers to regular fans by surprise, but slowly details are spilling out that reveal his true character. Specifically, sources say it was a well-known fact the TV anchor was unfaithful to wife Annette Roque throughout their 19 year marriage.

"He regularly cheated on his wife. Everyone knew. His wife lives in the Hamptons and he lives in the city, but we never heard he made unwanted moves," a source told People.

A Today show staffer corroborated those claims, but said that the sexual misconduct allegations are totally out of the blue and very unexpected.

"Everyone on staff knew he cheated regularly on his wife. That wasn’t a secret, but sexual [misconduct] is a shock. He was friendly and approachable with everyone, and was very well-liked," the staffers explained.

It sounds like Lauer used his power to woo the ladies, too, as "there was most definitely more than one affair and "they were never with anyone whom [Lauer] didn’t have significant seniority over," according to insiders.

"He wasn’t a lech and he wasn’t known as someone who would corner you or retaliate against you if you spurned him or someone who would lure you into his dressing room," the source insisted.

Lauer's wife filed for divorce in 2006, but they decided to reconcile.

Celebs have taken to social media to share their feelings on Lauer's scandal, and it sounds like nobody feels very sorry for him.

"HMMMMM INTERESTING…..THIS MIGHT EXPLAIN THE HOSTILE INTERVIEW WHILE I WAS TRYING 2 EXPOSE THE #TRUTH….EH MATT?” Corey Feldman wrote."Don't let the door hit you on the way out, Matt Lauer. "Today Show" #ROSEARMY," Rose McGowan said. "Matt Lauer has been on my list for a while. It’s really too bad more Americans don’t come to my shows. I pretty much recite the list in every show. Haha. I told you, my memory is long, my friends. I’ve been around a long time..." Kathy Griffin bragged.

Even our President is throwing in his two cents, even though he's the worst sexual predator of them all!

"Wow, Matt Lauer was just fired from NBC for “inappropriate sexual behavior in the workplace.” But when will the top executives at NBC & Comcast be fired for putting out so much Fake News. Check out Andy Lack’s past!" he tweeted, referring to the NBC Chairman who ultimately gave Lauer the boot.

If this #MeToo movement isn't teaching men to keep it in their pants, we don't know what is!
