On the upcoming episode of We TV's reality TV series "Marriage Boot Camp: Reality Stars," Athea Heart and Raymond "Benzino" Scott of VH1's "Love and Hip Hop: Atlanta" continue to argue and their relationship seems beyond repair, while jealousy breaks out as the couples are forced to swap partners in a dance exercise.

In the sneak peek for the episode titled "Dancing With the Devil," Scott and Heart are involved in another blowout argument, and Scott is seen packing up his bags, preparing to leave the house.

"I'm trying to be nice, like this is crazy," Heart cries as her "MBC" co-star, "The Bachelor" star Catherine Lowe, comforts her.

For their exercise, couples are to take part in dance lessons with their significant others. June "Mama June" Shannon of TLC's "Here Comes Honey Boo Boo" tries to dance with her husband Mike "Sugar Bear" Thompson, but he brushes her off.

"I'm watching, hold on," he says, sounding annoyed.

Meanwhile, Sundy Carter and her ex-husband Cedric, from VH1's "Basketball Wives: LA," also struggle with the exercise.

"You got work to do," Cedric tells Sundy. "I can't help you with everything, babe."

Camp counselor Elizabeth Carroll then drops a bomb and tells the couples that they will be paired off without their partners, which sparks jealousy in Sarah Oliver of Oxygen's "Bad Girls Club."

"I thought you were practicing with your new girlfriend," Oliver tells her boyfriend, tattoo artist Jimmy "Inkman" Coney.

"Don't say stupid sh--, you'll get cussed the f--k out" he tells her.
