Bachelor In Paradise suddenly suspended production in Mexico last week amid an investigation into alleged misconduct.

The fourth season of the ABC reality show started filming at a resort in Sayulita, Mexico on June 4.

Production was halted after a producer complained of 'workplace misconduct' after witnessing a raunchy hook-up in a pool between Corinne Olympios and DeMario Jackson, according to a report by ET.

Two sources tell People that Corinne may have been too drunk to consent to the sex act she had with DeMario.

'The show absolutely values the primacy of consent, and this instance it appears as though conduct allegedly occurred without the proper consent having been given,' one of the sources said.

According to people who spoke with DeMario, he claims that Corinne put her genitals into his face and that he began licking, TMZ reports. He also said he was too drunk to perform penetrative sex.

While Bachelor in Paradise is billed as a reality show, many aspects are often scripted.

DeMario said that before shooting, producers told him and Corinne that 'one of the story lines would be the two of them hooking up' - something that would be 'especially entertaining' because both were villains from their respective seasons.

According to DeMario and other sources, Corinne approached him on the first day of shooting at sat in his lap - proceeding to flirt with him and engage in some 'intense rubbing'.

'DeMario was in the pool. Next thing you know, Corinne comes over and hops on his lap. They start talking and joking,' the source said.

They soon got hot and heavy with each other as the cameras were rolling.

'That's when a "third party" felt uncomfortable, claiming misconduct in the workplace,' at source told ET.

According to DeMario's side of the story, the hook-up escalated in the pool when they both stripped down and 'started making out and "rubbing, touching and fingering."'

DeMario then claims that Corinne put her genitals into his face and he began licking. However, TMZ reports that that allegation is a 'big point of contention and others disagree with his account'.

DeMario said the two did not have sex because of the alcohol he drank.

The next day, he said he and Corinne were getting along fine when the two were taken aside by the executive producer.

The EP told them that one of the show's other producers had filed a formal complaint after watching the video reel from the previous night because he or she was 'uncomfortable' with what was shot.

Warner Bros. immediately suspended production and sent DeMario and Corinne home. Two days later, the rest of the cast was sent home as well.

'We have become aware of allegations of misconduct on the set of Bachelor in Paradise in Mexico. We have suspended production and we are conducting a thorough investigation of these allegations,' the statement said.

'Once the investigation is complete, we will take appropriate responsive action,' the statement added.

Corrine and DeMario have been in touch since the incident and are allegedly on good terms.

'DeMario was trying to reach Corinne via email, Instagram and Facebook for a few days. Finally, [he] got a hold of her, they exchanged numbers and they've been talking. They are both speaking and on good terms,' a source told EW.

Los Angeles Times film writer Amy Kaufman spoke to a source who told her that the show as effectively 'cancelled' because of what happened when Corinne 'got extremely drunk.

She said that the scene in the pool turned into 'soft core porn' and was 'very raunchy'.

The following day, a producer 'who witnessed this hook-up did not show up to work'.

Amy tweeted that the producer sued the production for misconduct based on what he or she witnessed, according to her source.

A source also told E! News that production was over for the season and 'possibly forever'.

Bachelor In Paradise was scheduled to premiere August 8 on ABC.

The summer series features previous contestants from The Bachelor and The Bachelorette who are isolated at an exotic resort in hopes of finding love.

The show starts out with an uneven amount of male and female contestants. At the end of the week they pair up and whoever doesn't have a partner is booted from the resort. One of a few new contestants is added after every elimination to turn the tables in favor of one sex.

The cast for season four included several women from the last season of The Bachelor including Corinne, runner-up Raven Gates, Alexis Waters and Jasmine Goode.

DeMario, who was booted from the current season of The Bachelorette for having a girlfriend, was added to the cast. Corinne was also an unpopular character on her season, but made it to the final four girls.
