This week on "The Real Housewives of Beverly Hills," Bethenny Frankel invited the ladies to her home in the Hamptons for dinner, and Erika Girardi got to experience what it's like to be on the receiving end of the Skinnygirl mogul's feisty side.

Bethenny was taken aback by Erika's wild side and she took shots at her alter-ego, Erika Jayne. The New York Housewife didn't hold back her opinions, and she even offered some unwanted criticism about Erika's music video, saying that she didn't love the production value of it and that it looked cheap.

For her part, Erika did her best to avoid getting into a fight with Bethenny, but she was seething during her on-camera interview. The dance-pop artist said that Bethenny wasn't in the music industry and that she shouldn't tell her what to do.

On her Bravo blog, Erika wrote a short message for her critics, saying that she is not ashamed of who she is or the lifestyle that she represents.

"I will not be fearful of what others think or say, because at the end of the day they do not have the courage to be themselves," Erika said. "They live in fear of being judged by those who are of little consequence."

Next week, in the episode titled "Going Deep," Kyle holds a book signing at her new pop-up shop for Bethenny and the ladies enjoy a final dinner in the Hamptons. Before they leave, Bethenny learns that she offended Erika and offers her an apology. Back in Beverly Hills, Lisa Rinna runs into an old friend with an intriguing past, and viewers will finally get to meet new Housewife Kathryn Edwards.

Kathryn is the ex-wife of NFL legend Marcus Allen and is currently wed to former football player Donnie Edwards. She is a former model from Wisconsin who appeared in a season 2 episode of "Married with Children" and also landed Nike's first "Just Do It" campaign.

In the season 6 trailer of" RHOBH," Rinna reveals that she has known Kathryn for a long time, and Kathryn reveals that her husband is nine years younger than her. It will be interesting to see how the newest Housewife gets along with the other ladies in future episodes.

"The Real Housewives of Beverly Hills" airs Tuesdays at 9/8c on Bravo.
