A Bachelor in Paradise crew member says Corinne Olympios seemed to lose control of her body during her drunken pool hook-up with DeMario Jackson.

Filming on the fourth season of The Bachelor spin-off was suspended on Sunday, over allegations of misconduct.

The incident that caused Warner Bros to halt production and launch an investigation centered on a hook-up between cast members Corinne and DeMario on the first day of shooting.

DeMario admitted to performing oral sex on Corinne when she put her genitals in his face, but Corinne says she was blacked out drunk and could not have given consent, according to sources who spoke to TMZ.

Now, a BIP crew member has spoken to DailyMail.com, detailing how Corinne appeared more and more drunk throughout the day.

‘Corinne and Demario found out when they arrived in Mexico that the storyline would involve the two of them hooking up so they decided to hang out and get better acquainted over drinks,’ says the source.

‘Soon they decided to go swimming and when they climbed into the Jacuzzi, they were both loaded. Corinne proceeded to remove her bathing suit and things got increasingly sexual.

‘There was hugging and kissing and touching, but before long, she seemed to go limp and was sliding under water. Demario kept trying to hold her up and at the same time he appeared to be having intercourse with her. After he finished – which only lasted a few seconds – he lifted her out of the water and laid her on the cement, where he proceeded to have oral sex with her.

‘She appeared to be unconscious,’ says the source. ‘At that point some of the crew came out and carried her off to her room. She was limp and seemed unable to walk on her own.'

For the record, DeMario told sources who spoke with TMZ that he did not have penetrative sex with Corinne because of the alcohol he consumed.

Another source told TMZ on Tuesday that Corinne was so wasted hours after the hook up that she could barely stand.

Witnesses said that two hours after the encounter, Corinne was 'stumbling drunk, eyes closed, slurring badly and wearing her clothes inside out'.

'She was on a whole other level,' the source said.

The show was suspended after a producer filed a complaint over what he or she saw of the drunken pool hook-up. Above, DeMario on the current season of The Bachelorette, before he was booted for having a girlfriend

The source that spoke with DailyMail.com said they were 'deeply disturbed...not just at what happened, but over the way it was handled.'

‘One of the things that really disturbed people was that no one called a doctor or paramedic, which some felt they should have. Instead someone made the decision to just let her sleep it off.

‘When Corinne awoke the next morning, people began filling her in on what happened the night before, because she claimed to have absolutely no recollection of what transpired,' the source said.

Since filming was suspended, the source says that the set has been turned into a crime scene and that investigators with the Los Angeles Police were even called to look it over. Doctors and psychologists were also brought in to interview everyone about what they saw. The source said that lawyers deposed those who witnessed the hook-up and told the cast and crew not to speak out about what they saw.

‘Corinne is preparing to file a law suit because she feels she was not protected by the show’s producers. And she ended up flying home to Miami after she was examined and interviewed,’ says the source. 'She was totally distraught and even after being told what happened, she insisted she had no recollection of the events.

Corinne 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.

Sources who spoke to Corinne also say she doesn't blame DeMario fully for what happened. She thinks the producers were at fault for letting the incident unfold and has hired a lawyer to represent her going forward.

The crew stayed on until Monday, when they back to Los Angeles. The source says that everyone is under the impression that the show will be cancelled 'because the brand will be too tarnished to move forward'.

‘There were also rumors early on that they were going to scrap the show and offer Corinne a show of her own, or try and switch to filming a hurry - up wedding between last year’s contestants, Evan Bass and Carly Waddell who are engaged, but in the end they abandoned both ideas, paid off the crew, and sent them home.

‘This was a terrible thing to happen on a show that has been so successful until now,’ says the source. ‘And you can bet this is far from being over.’

The day after the hook-up, a producer filed an official complaint over what happened on the set and production was shut down.

Warner Bros announced that production had been suspended in a statement on Sunday.

'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.

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.
