Vicki also tells TooFab about her relationship with Tamra Judge and teases an "outburst" from one of the newcomers.
The trailer for the new season captures an explosive argument between Vicki and Kelly Dodd over Vicki's decision to go on a double date with her boyfriend, Steve Lodge, and Kelly's ex-husband, Michael Dodd. Kelly did not take the news well, which Vicki said shocked her given how well Kelly's adjusted to life post-divorce.
"I was kinda like, 'You divorced your husband, and you didn't want him, so why do you have any emotions?" Vicki said when she stopped by Studio TooFab Monday. "It made me realize that maybe she's still in love with him. I didn't have those emotions when I divorced Donn. When Donn started dating people I knew, I had zero emotions. I was like, I want the best for him. If he wants to date a friend of mine, go for it. I didn't feel like, 'Oh, because I divorced you, you can't be with anybody else.' So it made me really realize that I think Kelly's got stronger feelings for Michael than she wants to really say."
Vicki also doesn't think she broke "girl code," but Kelly sure does.
"It really wasn't Kelly's business who Michael was dating," Vicki said. "Kelly got her feelings hurt really bad, and I had no idea that she could be that emotional about it, but I was in a really tough spot. She said I broke girl code, but my girlfriend, Terri, asked me not to tell Kelly, so who do I honor? I've known Terri a long time -- longer than I've known Kelly. I didn't know it was girl code."
"If Michael and her were married and I set him up with somebody and they were cheating, then yeah, that's horrible," she added. "Or if I dated Michael, that's horrible. But we were just very platonic. It was just four of us going out to dinner a couple of times. It wasn't a big deal."
Last month, Tamra Judge chatted with TooFab about the status of her relationship with Vicki moving forward from last season's explosive reunion. She said the two were working toward rebuilding a friendship but that she wanted to remain "cautious."
"I'm very cautious as well," Vicki said. "Once you've been so hurt by each other, there's only one way to go back into it -- to be cautious, to be guarded and really to have learned from our mistakes that we both did. I'll own mine, and she owned hers, and I think it was easier now being cautious, because if we went all in and just became completely transparent again and not be careful of the words we choose, we would've fallen right back into that same pattern."
Vicki said her relationship with Shannon Beador has also made great strides and that viewers will get to see them see each other for the first time since the reunion on Monday night's premiere.
The Season 13 trailer also shows Tamra cornering Steve and demanding he marry Vicki. Steve ends up storming off, but Vicki assured us there's no trouble in paradise.
"We're two-and-a-half years now, and he still likes me!" she joked. As for her controversial ex-boyfriend, Brooks Ayers, Vicki said he lives only in her past.
