"I was wrong -- I called them animals. I called them -- their act was trashy for doing it," Siggy explained to Andy Cohen on Wednesday's "Watch What Happens Live," adding that she had had more than two drinks that night and acted "in the heat of the moment."
"I'm very dramatic, I have a lot of energy and I get very excited," she added. "But for me, once the cake was thrown, it was over for me."
Sitting next to Flicker was Valerie Bertinelli, who interrupted the New Jersey firecracker to suggest that the ladies reimburse her for the cake.
"No, I just wanted them to say I'm sorry," Siggy replied. "I'll eat the cost. I don't care about that, but friendships and relationships are 50-50. It was more like this is the way we act."
What really bothered Siggy was that "nobody wanted to apologize."
"It was disrespectful to not only the cake maker, but it was disrespectful to the restaurant," she added.
When a caller asked Siggy -- a relationship expert -- if she thinks Teresa and Joe's marriage is going to last, Siggy was forthright as ever.
"I happen to think that they will," she said. "Believe it or not, I do. I don't know, call me a hopeless romantic. I think that Teresa is out there every day busting her butt for her children to put food on the table, to do what she has to do. I've never met a stronger woman, and I think that when Juicy Joe comes out and he's lost over 55 pounds -- he's looking good -- I think that she's gonna stand by her man in the end. Yes, I do."
