The Marcheses are really making a splash with their return to reality television!

"The Real Housewives of New Jersey" alum Amber Marchese revealed during the Oct. 28 episode of "Marriage Boot Camp: Reality Stars" that she once cheated on her husband, James "Jim" Marchese, with another woman.

"I had an affair with a girl," Amber admitted during the episode, which centered on "Love & Hip Hop Atlanta" star Margeaux Simms' relationship with girlfriend Merika Palmiste.

"Jim got pissed," Amber continued. "To me, it was like no big deal. It was like, 'So what?'"

Infidelity isn't the only issue between the former Housewife and her hubby, though. On last week's episode of the WE tv series, Amber and Jim argued over his proclivity for alcohol.

"You drink too much, and I tell you that," Amber told her husband. "Stop f------ drinking."

Amber and Jim were featured on the sixth season of "The Real Housewives of New Jersey" in 2014 but reportedly quit when they became unhappy with the way they were portrayed on the show.

In November 2015, the mother of two, who's also the stepmother of Jim's two children from a previous relationship, complained to People magazine that she felt the series didn't give viewers the opportunity to get to know the real her.

"The show was not what we expected it to be, and I want to pursue more suitable endeavors," she said at the time.

Since then, Amber has appeared on just one episode of Season 7 of "The Real Housewives of New Jersey." She also popped up on Theresa Giudice's three-part Bravo special "Theresa Checks In" in 2015.

But just because the cameras weren't rolling doesn't mean the drama stopped.

On April 19, police arrested Jim for felony domestic violence after he allegedly grabbed Amber by the throat during a pre-flight altercation aboard a Virgin America flight at LAX Airport in Los Angeles. The duo were removed from the plane in cuffs by LAX Police Department officers, but ultimately, Jim was not charged due to lack of evidence against him.

The couple are now suing the airline for false imprisonment and defamation. They claim they were engaged in flirtatious behavior -- and were joking about joining the mile-high club -- when a flight attendant misinterpreted their behavior and involved the authorities.
