On a plain black background, The Bachelorette told fans to prepare.
"Tonight's episode of The Bachelorette contains images of a graphic nature, including scantily clad men thrusting and gyrating," they wrote.
"If you have a weak heart or raging libido, viewer discretion is advised."
The post was captioned, "WARNING: Tonight's episode of #TheBachelorette is steamy. Prepare accordingly."
This will only be the third episode of Season 21 and fans are threatening to boycott.
The Bachelorette airs on Mondays at 8pm on ABC.
'IT'S GROSS'
Fans commented on the post and said how "gross" and "lame" this content is.
"You guys do this every season. It's not cute or funny, it's lame and kind of gross," one Instagram user wrote.
"This may just be my final straw with this show. I watch it because it’s mindless and fun, but this is just unnecessary and gross," said another.
"This is gross. It’s not cool when you objectify the women, but it’s also not cool to do it to the men," added a third.
"1st season I've chosen not to watch. I'm extremely disappointed!" a Bachelorette fan commented.
"This is why I’m not watching the show anymore! I used to be a huge fan," a follower wrote.
"For one, gross… and two, whoever wrote this could’ve worded it a little better bc what in the world?" said one last fan.
START YOUR ENGINES
Host Jesse Palmer shared the warning on his Instagram Story and then shared the preview for the spicy episode.
"Tonight, start your engines," a voiceover said.
Three of the men were seen in racecar attire, and the Bachelorette Jenn Tran, took her hair out of a helmet and waved it around.
"Let's get down and dirty," Jenn was seen saying in a confessional.
After the men were done on the racetrack, they "brought the thunder."
Jenn fanned herself as her suitors stripped in front of her.
They ripped their shirts and threw off their pants.
"It's a little hot in here," one said, taking off his pants, to reveal tighty whities with "Jenn" written across the butt.
"Someone get me a towel," Jenn said, as she fanned herself in a confessional.
The trailer ended with the suitors arguing in the mansion and Jenn telling them that if they don't think this is the place they should be, then they should get out.
