On last night’s Real Housewives of New Jersey, mob heiress/former reality star Victoria Gotti made an appearance, complete with a bombshell allegation about new cast member Teresa Aprea’s marriage!

She claimed the reality star’s husband, Rino, previously had an affair with Teresa’s mother Santa (A.K.A. his mother-in-law)!

“He started talking about his divorce,” Victoria said, recalling a conversation she had with Rino back when he and Teresa were divorcing (they then got remarried seven years after their break-up).

“He said, ‘it’s who I cheated with.’ He just looked at me and he said, ‘Her mother.’”

While Teresa didn’t directly address Victoria’s shocking (and somewhat disturbing) allegations, she made her feelings about the Mafioso relative very clear with a cryptic Instagram post.

“Ignore those people who are constantly talking about you behind your back because they are right where they belong,” it read. “BEHIND YOU.”

She also retweeted fans who voiced their doubt about Victoria’s shocking allegations.

“You’re dealing with garbage. No one believes. Stay strong,” one such tweet read.
