The distasteful comment came during a fight between the two housewives, which prompted the 20-year-old to share a post which was written by her mom’s business manager to address the situation.
"I don't comment on the show, ever ... Mostly because opinions are like a**holes. But this needs to be said, heard and repeated," Teresa's business manager, Karianne Fischbach, said in an Instagram post shared by Teresa and Gia.
"As a grown a** 'I'm so so smart I'm a lawyer' woman to bring Gia's name into an argument and place an accusation with such a weighted consequence is inconceivable," the statement read.
"What the cast members choose to do to [with] each other is the nature of the reality TV beast, this was too far."
The drama began after Teresa said she heard a rumor that Jackie’s husband, Evan, was having an affair during his birthday party.
"I don't know if you made it up or if someone really told you, but you need to admit that whoever told you this doesn't know me and Evan and gave you no evidence of anything," Jackie said when she confronted Teresa.
However, Teresa did not say whom she heard the rumor from. "I never asked for evidence," she said. "I'm just letting you know that somebody let this out there."
"I heard that Gia snorts coke at the bathroom at parties! I heard it! I don't know who I heard it from. I heard it from somebody," Jackie said when Teresa did not "clear" Evan’s name.
"I did not watch this but totally agree a GROWN woman should never use an analogy like this," Dina Manzo added. "Especially about our beautiful Gia. Jackie needs to make a public apology immediately."
"I think that it was terrible to bring in [Gia]. It’s one thing when we’re talking about us, it’s another thing when we bring kids in," RHONJ costar Melissa Gorga told Us Weekly about the incident. "I never want to bring [up] a child — even if they’re 18, whatever, however old they are. I mean, I know Gia is 20 now. It doesn’t matter. All of our kids to me are always off-limits."
"First of all, she didn’t even say like, 'How would you feel if I had said [this about Gia]?' It wasn’t even articulated in that way. It was a statement," Jennifer Aydin commented. "And even though I know what her intention was, saying that about someone’s child —an innocent child that really has nothing to do with this No. 1 — [and] No. 2, let’s not forget that Jackie came for Teresa’s husband on more than one occasion."
"My analogy about Gia was simply an analogy — there was no truth to it of course. The rest of the cast understood this, which you'll see in the coming weeks,” Jackie explained as she wanted Teresa to understand how hurtful rumors are.
"The behavior at my husband's birthday party is truly unfortunate — destroying a marriage and family is not entertainment."
