It's rare for a "Real Housewives" cast member to admit they're wrong, but Heather Dubrow of the "Real Housewives of Orange County" did just that. And she took it one step further: she admitted her behavior was out of line to her enemy Alexis Bellino. 

But in "Real Housewives" fashion, DuBrow's apology came with passive insults. 

Bellino has quit the Bravo series and will not appear on season eight of the popular show despite being given a "generous offer."

Her resignation, broke out a war on Twitter.

On Oct. 4, Twitter account @RHOGossip linked to a story of Dubrow denying that Bellino quit and that she was, in fact, fired.

Bellino tweeted to Dubrow, "Do I need 2release my offer letter 2the media & make u look like a fool? Stick to what you know HD...being mean."

"When you are offered a return & you ask 4 more $ & they say 'never mind'. That's a clue . I'm honest, not mean," Dubrow tweeted on Oct. 5.

Barney then joined in the conversation on Oct. 7: "exactly! When an offer is rescinded because you're too difficult to deal with = you're fired , Not your choice!"

Bellino defended herself: "Wrong again!This behavior both of u r showing is exactly why I said no! #stopbullying!"

A fan of the show then added,"alexis it's not bullying, it's calling you out!"

On Oct. 8, the former Orange County housewife replied, "No, you haven't walked in my shoes,& even when I quit, they don't leave me alone. Bullying is not cool on any level."

But DuBrow tried to settle the Twitter feud on Oct. 6 with the statement: "This is getting out of control. Truly beneath us both @AlexisBellino. I wish you and your family well. Good luck in your future projects."

Of course, Barney, always the pot-stirrer, wrote "@HeatherDubrow ignore her she is trying to stay relevant now that she dismissed. ... liars and fakes don't make it far in life."

But Dubrow told WetPaint Entertainment she is not proud of her Twitter outburst, but she got "a little hot under the collar" because she thought Bellino use of the term "bullying" was not justified.

"I think this is the bottom line: I don't like the term bullying being bandied about like this. Bullying is an incredibly serious issue, and it's just not applicable in this situation," Dubrow told WetPaint Entertainment.

Dubrow, however, indirectly said Bellino should have a thicker skin by now since she's been on the show for three years.

"When you sign on to be on a reality show, you understand that it's your role to have an opinion. It means that if you're someone with filters, you need to take your filters out and say what it is that you're thinking. Because it's all about relationships and opinions and being vocal about them. And I think Alexis, having been in her third year this past year, is cognizant of that fact. So, I think, my perception is that when it turns on you and it's not working out for you, it's very easy to run to the corner and cry victim. But that's just not that case. You know, this is the show. The show is about relationships and opinions. We all go into it with open eyes. I'm done discussing this. As far as I'm concerned, the Alexis chapter is closed. I wish her well and her family. I have no ill feelings. I really don't. And listen, everyone moves on."

Dubrow did take a jab --it's yet to be determined if it was intentional or not -- at Bellino when she was asked, "How do you think the dynamics will shift in the group with Alexis gone in the hypothetical eighth season?"

"I don't know. I think it takes a lot of the pettiness out of it," she said. "And I hope that if we do go forward and they do bring other people on, it'll obviously change the dynamic, and I'm not saying everyone's going to be all flowers and ponies but I hope that the audience can see some of everyone's best self and really see the relationships instead of worrying about little petty things."
