Kelly Dodd is firing back at “The Real Housewives of Orange County” star Gina Kirschenheiter.

“#rhoc @GKirschenheiter don’t feel sorry for me!! I feel sorry for your 6 kids being packed into 2 bdrms!!” Dodd, 46, tweeted on Wednesday.

She went on to brag about all the material items and experiences she’s been able to give her only child, 15-year-old Jolie, whom she shares with ex-husband Michael Dodd.

“My daughter has traveled the world, lived in the best places & houses & had the best education!!” Dodd added before taking a shot at Kirschenheiter’s latest business venture.

“Go on w/your fake skin care line you can buy at Rite Aid #salicylicacid.”

The heated tweets were posted shortly after Kirschenheiter, 37, appeared on “Watch What Happens Live with Andy Cohen” and slammed Dodd, saying she felt “worse” for her than she does for frenemy Shannon Beador.

Kirschenheiter — whose Season 16 tagline is “I’ve still got a small house, but I’m living large!” — made the remark after Cohen told her Dodd had called her a “charity case” who never hosts parties or events.

“I mean, I just don’t even care. She didn’t host anything, either, and she’s just, I don’t know. I feel worse for her than I do for Shannon,” Kirschenheiter, told Cohen, 53.

“My argument would be, yes, OK, I didn’t host anything, so I guess you’re saying I’m just enough without hosting anything or the money and the over-the-top stuff. Sorry I’m enough, ya know?”

Dodd — who co-hosts a podcast with her husband, Rick Leventhall, dedicated to trashing weekly episodes of “RHOC” — went on to call Kirschenheiter “fake fake fake” in response to a fan who claimed “Gina threw Kelly and Shannon right to the side for Heather [Dubrow]” and that “those are the girls you have to watch out for.”

Kirschenheiter and her ex-husband, Matthew Kirschenheiter, share three children: Nicholas, 9, Sienna, 7, and Luca, 5.

After only six months of dating her current boyfriend, Travis Mullen, the two moved in together and brought their “Brady Bunch” with them.

Mullen has three children, two daughters and a son — ages 10, 8 and 5 — from a previous relationship.

The reality star has shown off the modest home they share on the current season of “RHOC.”
