Last week, Shannon Beador posted a very heated reaction video to Vicki Gunvalson's claims that she too was duped by her ex Brooks Ayers. Now, Heather Dubrow is giving her take on the situation, telling Entertainment Tonight that Vicki must apologize for lying about her ex's condition.

All throughout the 10th season and reunion show of "The Real Housewives of Orange County," the ladies questioned Brooks's cancer claims, suggesting that he was faking his illness. On last week's "Watch What Happens Live," Vicki told Andy Cohen that she was also deceived by her ex. She also said that she wanted to apologize to the ladies as she feuded with some of them during the recently concluded season of the Bravo show while defending Brooks. In her Facebook video, Shannon said that she never received an apology from Vicki, and Heather is echoing the mother of three's sentiments.

"She hasn't apologized for lying," Heather said to ET, "and I think for the rest of the cast, it just leaves a really bad taste in our mouth."

While Heather believes that Vicki was "duped" by Brooks, the former actress said that she also believed that at some point, Vicki knew that Brooks was lying about his cancer and wished that Vicki would just admit it.

"I just wish she would come clean, so we could all go, 'OK, we get it. It happened. Let's move on,'" she said.

Moving on seems to be among Vicki's agenda as following her appearance on "WWHL," the reality star chose not to respond to Shannon's video. Instead, Vicki turned her focus to a new venture and she launched a new perfume earlier this week called V by Vicki.

Heather thinks that the timing of Vicki's perfume launch seems to be very odd since she just made conflicting statements about Brooks's cancer.

"I think coming out with products and things when you're in this sort of position, it's just sort of odd timing to me," said Heather.
