Chris Brown has been charged with savagely beating his ex Rihanna, but one groupie says the R&B star is "disrespectful towards women" after harrowing night on Brown's tour bus. 

Radar Online has an eyewitness account from a former Chris Brown fan who was invited on his bus after a concert in Boston. 

Jessica Hehr said that her friends were invited onto Chris Brown's bus after a show in downtown Boston. 

But things seemed off the moment Jessica, a high school senior, and her friends were asked to turn in their phones and their shoes before being invited on the Chris Brown tour bus. 

"But when we got outside they had taken our phones and shoes away from us and to be honest we were kind of in a daze, this had never happened to us before so we kind of just went along with it. Stupid move." 

Once on the Chris Brown tour bus, things escalated pretty quickly and Hehr was uncomfortable, particularly with the way Brown and his boys acted towards the women in their presence. 

"I kept quiet the whole way and pretended like I was having fun. There was drugs, alcohol and a lot of rapping. But they are also very, VERY disrespectful towards women," said Hehr.

"The only drug I physically saw was marijuana. Chris has some vodka brand called Zing and they would pour it down our throats. Well, they did it to my friends but when it came to 'my turn' I took the bottle and pretended I was drinking out of it because I wanted to have my senses and remember things from that night."

"What really opened my eyes was how Sean, Chris, and all of their friends treat women," Jessica continued.

"On the bus it was just my roommate, another friend, and myself. But there were also two girls who Chris took with him into his hotel room.

"One of the guys on the bus pulled my friend over and lifted her skirt all the way up and started hitting her behind.

"While my roommate and I were trying to pull down her skirt, all the guys including Sean [Kingston] were slapping her behind while Chris was just looking right at her and laughing very, very hard."

Awful. 

The college senior and her friends eventually left the hotel room in Foxboro after a secret meeting in the bathroom. Chris' misogynistic friends chased them down the hotel hallways, but ditched the pursuit when they spotted some cops in the lobby. 

"They took the elevator down with us, but once they saw we were going straight to the cops they dispersed. Chris was already in a room with those two other girls from the bus," claimed Hehr.

Brown is back with his ex, Karrueche Tran, and she was recently spotted in a form-fitting black bikini while on vacation in Miami, but you can only imagine her surprise and disgust when she read this awful recount from Hehr.

Rihanna was smart to get away from Brown when she did. Chris Brown is a sexist louse, and Tran will dump him soon enough, but the lesson, as always: don't get on Chris Brown's tour bus, no matter what!
