US Bachelor series suspended after an alleged sexual assault played out on camera.

When it comes to reality TV, we’re used to a bit of scandal.

Whether it’s hints of who’s won before a competition has even started, contestants calling each other names or “cheating scandals,” it’s all part and parcel with letting your every move be filmed for the entertainment of complete strangers.

Except of course, when the “scandal” becomes something more sinister, which is exactly what’s happened to the latest season of Bachelor in Paradise, a spin-off of the popular reality dating show in the US.

The show centers around a seemingly never-ending supply of ex-Bachelor and ex-Bachelorette contestants who pair up in an attempt to find love with the help of a romantic tropical destination.

Yesterday, it was announced that filming of the show, which just began in Mexico, was suddenly halted.

The studio behind the show, Warner Bros., issued a statement that producers had become "aware of allegations of misconduct" on the set and that production was halted so that a thorough investigation could be completed.

According to People, two contestants were filmed in a sexual encounter in which one may have been too drunk to consent.

"The show absolutely values the primacy of consent and in this instance, it appears as though conduct allegedly occurred without the proper consent having been given," a source told the publication.

The female contestant in question has not been named. According to Entertainment Tonight, contestant DeMario Jackson, recently booted from the current season of The Bachelorette after it was revealed he already had a girlfriend, was involved.

Joe once said, 'I don't wanna be a player no more' on the Hip-Hop classic, 'Still Not a Player' and after 30 summers of being single and a player on and off the court I'm feeling like Joe.

Apparently, other contestants witnessed the encounter and were upset when producers didn't attempt to stop or de-escalate the situation.

"People are pissed, and not just at DeMario," a contestant told People.

"We're pissed that this whole thing happened," the contestant added. "They could have seen that she was drinking too much and that he was taking advantage. They could have stopped this before it got this far.

"But they decided to let it go, and let it happen, and see what happened? So, I'm angry at the show, and everyone else is too."

The show was due to premiere in the US on August 8, but it looks like fans will be waiting much, much longer, with some sources even saying the show will be cancelled for good.

For the record, one thing I can report to be 100% true: This season of Bachelor in Paradise isn't happening. It's been cancelled.
