Lisa Vanderpump isn't moving on from the things she heard Camille Grammer say during a recent episode of "The Real Housewives of Beverly Hills." Although Grammer offered her co-star an apology for her comments after the episode in question, Vanderpump is holding a grudge and recently responded to a fan who said there were no excuses for Grammer's behavior.

According to the fan, who shared a message on her Twitter page days ago, Grammer should have never shared such mean statements about Vanderpump's teeth on the show, regardless of how much alcohol she drank.

The fan then said that a true friend doesn't make up lies about her in an effort to laugh at their expense, and Vanderpump agreed.

"Exactly!" Lisa Vanderpump tweeted back at her, adding that Camille Grammer's comments were "sooo hurtful." "And she said it was a joke," Vanderpump continued. "We could all say anything."

Camille Grammer apologized on Twitter

After the episode of "The Real Housewives of Beverly Hills" aired on Bravo TV earlier this month, Grammer expressed regret over her distasteful comments on Twitter as she shared a series of messages with her fans and followers.

"It was a bad joke and a needed [change] from [puppygate]," she explained. As fans well know, the ladies of the show have been at odds for the past several weeks over who was behind a leaked story about Dorit Kemsley and Lucy, a chihuahua mix she adopted from Vanderpump Dogs, which is Vanderpump's animal rescue center in West Hollywood, California.

"I was trying to bring some levity," Grammer continued in her apology tweet. Grammer then said that her co-star has beautiful teeth and added that there is nothing wrong with her gums.

Grammer supported Vanderpump's restaurant

Just weeks before Grammer's shocking rant against Vanderpump aired on the show, Grammer showed up to her Las Vegas restaurant, the Vanderpump Cocktail Garden, as the only cast member to offer their support to her.

Although Joyce Giraud was also in attendance at the event, as was the "Vanderpump Rules" cast, Giraud is not a current cast member on the show and hasn't been since the series' fourth season.

During her time in Vegas with Vanderpump, Grammer shared a series of photos of the Vanderpump Cocktail Garden event, which was held at Caesar's Palace, on her Instagram page. In one of her photos, her daughter, Mason Grammer was seen.

To see more of Lisa Vanderpump, Camille Grammer, and the rest of the "Real Housewives of Beverly Hills" cast, don't miss the new episodes of the ninth season of the show, which air every Tuesday on Bravo TV at 9 PM.
