'Bachelor Nation' Bombshells: The Biggest Scandals in the History of the Franchise

Corinne Olympios and DeMario Jackson may be the latest stars from Bachelor Nation to spark controversy on set, but they're definitely not the first.

Production on season four of Bachelor in Paradise was suspended this week following allegations of misconduct. A source told ET that the two allegedly started hooking up in the pool after the cast had been "drinking all day," and that a "third party" felt uncomfortable, claiming misconduct in the workplace.

Drinking on BIP isn't anything new. Since season one, the contestants have had access to a full bar with unlimited alcohol. So for production to completely shut down?

"It's crazy," another source told ET. "It's a multimillion-dollar production."

Amid what actually may be the biggest scandal in the history of this show, ET is breaking down the biggest Bachelor Nation bombshells of all time, from Bachelor in Paradise, The Bachelor and The Bachelorette.

1. A contestant is accused of having an inappropriate relationship with a producer.

During Jake Pavelka's season of The Bachelor, things got a little crazy on set when Rozlyn Papa was accused of flirting with a man who worked behind the scenes.

"The only thing this has to do with was your inappropriate physical relationship with our producer," Harrison explained to Papa at the time.

"What was this physical relationship?" Papa asked. "I'd like to know all about it, please."

After a fellow contestant claimed she saw Papa and the producer kissing on the stairs, the two were booted from the show.

2. Pavelka accused of emotional abuse.

That same season, Pavelka chose Vienna Girardi as his final pick and proposed to her during the finale, but things took a twist during After the Final Rose. Girardi stormed off set crying and yelling, "You don't love me" to Pavelka after he urged her to "stop interrupting" him during their sit-down interview with host Chris Harrison.

3. A Bachelorette reveals her final suitor ahead of the finale.

While season 11 of The Bachelorette was still airing on ABC, Kaitlyn Bristowe accidentally spoiled her season when she posted a photo on Snapchat of her in bed with her now-fiancé, Shawn Booth.

"Trust me, that was not on purpose," she later explained.

4. A meltdown in Mexico.

Many fans were stoked when they heard the resident villain from JoJo Fletcher's season of The Bachelorette, Chad Johnson, was heading to Bachelor in Paradise. Unfortunately, his time on the show only lasted 24 hours.

Johnson was sent home after drinking heavily and trying to fight Harrison, as well as his castmates.
