Sylvester Stallone. I need to stay vague to protect a friend's identity, but he runs a high-end travel outfit that basically does arrangements for the super-rich in a nice tropical location.

So Stallone stayed at a very swanky resort. He checks out-there's poop in the tub. They let it slide because it's Sly. Next visit-more poop in the tub upon checkout. This time, they warn him not to do it again. Final visit-more poop and permanent ban from resort.

I can tell you right now that Sully from Godsmack will try to fight you if you ask "Can I have your autograph Scott Stapp?"

Andy Griffith would shoot at you if you trespassed on his property.

My grandpa lived nearby and said that Andy was always shooting at people.

Someone I know met Adam Levine backstage and was pissed because he told Adam”you guys are good” Adam said “ I know” and walked off. I thought it was funny because this guy took it so personal

Bill Nye. Granted in the last few years he's revealed himself as a self centered jerk but I am reminded of a story from a podcast a few months back:

A girl was working retail at a clothing store and Bill Nye walks in. He ends up at her register and she says something to the tune of "Hi Bill, I just wanted to say I appreciate what you did for getting kids into science, I grew up watching your show!" Bill replies, "and look where that got you."

Ellen DeGeneres.

As soon as the cameras are off she turns into a tyrant. Her staff is in constant fear of her and she yells at everyone.

Bill Murray. Difficult to work with. There's a reason Harold Ramis refused to work with him again after Groundhog Day, in spite of all their success together.

I know this will be the shocker of shockers, but Matt Lauer was apparently a horrendous douche. I have a family member who worked at NBC and said that Lauer allegedly was a petty tyrant and gave off creepy vibes (this was back in 2011ish).

On the flip side, she said Conan is among the nicest people she's ever met. So, yay!

In the 90s Michael Jordan marketed himself as the "role model" basketball player for kids while Charles Barkley, who was kind of a troublemaker, famously told kids he was "not their role model".

Now when you hear stories about the two players you realize that MJ was/is a gigantic a**hole while Barkley is one of the nicest men in sports.

One of my friend's parents were extras on Legally Blonde 2. According to them, Sally Field is not a nice person at all. On the other hand, Reese Witherspoon, they said, is an absolute delight.

Jamie Kennedy

2002 I won a trip to miami for some contest Axe had after I clicked an internet banner (yeah, they work, but also I had to pay $1200 in taxes). They set up a house party at Jamie Kennedy's house and when I approached him he gave me a sneer and walked away.

Conversely, Seth Green, who was also there, was awesome. His manager or whatever she was started to turn me away thinking I wanted an autograph, when all I wanted was to say hi. He heard me explain and turned around to shake my hand and talk for a few seconds, gave a bow, and continued his conversation that I inadvertently interrupted.

My wife worked with Kate Bekinsale. Apparently she is a raging b**ch. She also worked with Terry Crews, and I met him a few times, and he is every bit as sweet and positive as he seems.

Katherine Heigl. Don't let all those old rom-coms fool you, there's a reason she's not around anymore.

All I can say is that James Corden has come into my work 3 times, I’ve politely said hello to him (not in a “HELLO THERE MR. JAMES CORDEN FROM TV AND MOVIES” kinda way, but just a general polite customer service “hi there, sir, welcome” way) and of those three times, he’s said hello back 0 times. Not even a smile, just a quick neutral-face glance.

Alicia Keys: I worked security at a local concert venue for over 10 years and she was hands down the meanest artist that I rubbed elbows with. One night, I was asked to stay late and work a meet & greet in the catering trailer after her show. I stood next to Alicia and her assistant at the time (guessing 2006) while she met a group of fans one by one. Each fan gave her gifts/flowers and had roughly 30 seconds to say hello. Being so close, I was able to hear every word she said to her assistant and it wasn't pretty. She basically bad mouthed the entire group - she had something negative to say about almost everyone's outfits and appearance. Considering how long ago it was, here is to hoping that she has grown up since then.

Frank Sinatra once called my grandfather an a**hole at a blackjack table just for sitting there.

Sugar Ray tried to fight a kid who called him Sugar Gay.

I don't actually think this makes him an a**hole or even not nice, sometimes you just want a drink in peace, but it's a funny story.

My friend met Patrick Stewart in a pub during his stag do. Since it was a stag they figured they should make it memorable so his friend approaches Sir Stewart and says "I'm sorry to ask this bu..."

Stewart interrupts him and says "Then don't."

His friend sheepishly walks back to the party...

Tickled me anyway.

I don't even know if he seems nice but Shia labeouf is an a**hole.

Work security for a company that does movie screenings and security details for actor that come to do Q&A's. Worked with him on his movie "Man Down" and we all walked out on him and left him on his own. He was very verbally abusive and constantly yelled and cussed us out. So we said f**k it and left.

A friend of mine ran into Hugh Jackman at a cafe and didn’t recognise him (she is fairly old and doesn’t watch movies) but knew she knew him from somewhere, and spent the next twenty minutes or so asking him if he was various members of her distant extended family. He was very polite and seemed to find it more amusing than anything else. He eventually owned up and was pretty embarrassed (but not at all haughty) to have to explain he was a movie star. Apparently just an all-around class act.
