Former Real Housewives of New Jersey star Danielle Staub returned to Bravo for one night to appear on Andy Cohen's Watch What Happens Live on Sunday.

Surprisingly, Staub expressed sympathy for Teresa and Joe Giudice -- even though Teresa famously flipped a table and called Staub a "prostitution whore!" on the RHONJ.

"I feel bad for them," she told Cohen. "They’re people. They’re family. Things that are really bad are happening to them so it would be really wrong of anyone to enjoy that."

"I love Teresa," Staub revealed. "I have absolutely no problems with Teresa."

Funny enough, Staub has no affection for Teresa's sister-in-law, Melissa Gorga.

Staub confirmed they'd never actually met, because Gorga came onto the show after she'd already left.

“We did never meet, however, it was because I wouldn’t allow that to happen,” Staub said.

“She wanted to film during season two and she thought it would be a good way to get back at Teresa and I said I wanted absolutely nothing to do with that, however, I would forward all her emails, which were a lot, to the producers, which I did, which is how with two seasons of her being behind the scenes, on camera but behind the scenes, she all of a sudden became a person of interest and that’s how she landed on the show," Staub added. “I think it would be good for her to just come clean. I wanted nothing to do with what she wanted to do to Teresa. It’s not my place. I don’t play with that. Karma has a return policy and it isn’t an exchange.”
