Kim Richards: Harry Hamlin Cheated On ‘RHOBH’ Star Lisa Rinna [Report]

Kim Richards and Lisa Rinna did not hit it off during filming on the fifth season of The Real Housewives of Beverly Hills. In recent weeks, there have been several rumors regarding the pair’s ongoing feud. In the latest report, Richards has allegedly made claims that Rinna’s husband, Harry Hamlin, cheated on her.

According to a source, Richards and Rinna’s fight at Adrienne Maloof’s party, which the Inquisitr reported on last month, included more than just threats by Rinna.

“Kim had heard rumors for awhile that Lisa Rinna’s husband, Harry[,] had been unfaithful,” a source told Radar Online on November 5. “Upon hearing the claim, Lisa went nuts, and immediately lunged at Kim. There are certain things that are just off limits as far as Lisa is concerned, and Harry is on that list.”

Although Richards’ didn’t reveal where she got her information, the source appeared convinced that the accusation was unwarranted and was something Richards said in an effort to get back at Rinna for her reported relapse concerns. “The accusation was made after Lisa became very suspicious that Kim had fallen off the wagon during the cast trip to Amsterdam,” the source explained.

In the recently-released trailer for The Real Housewives of Beverly Hills, Rinna was seen making it clear that Hamlin isn’t someone who wants to be dragged into the ladies’ drama. “Don’t you ever go after my f******g husband,” Rinna is seeing yelling at Richards in the clip.

During Maloof’s party, which was held in Los Angeles on October 22, “Lisa attempted to push Kim, and the women had to be physically separated,” Radar‘s source claimed. “Lisa even made threats against Kim. It was totally crazy.”

Despite her accusations, Richards was reportedly taken back by Rinna’s response to her comment. “Kim didn’t think Lisa would have such a violent reaction, and it really shook her up.”

Now, Rinna has promised “to get revenge on Kim and expose even more lies when the cast reassembles to tape the reunion of the show in the next few months. Lisa is a real firecracker and Kim opened a can of worms she will regret opening,” the insider stated.

As the Inquisitr reported in September, Richards dealt with some medical drama while filming Season 5. However, following her days-long hospital stay, which the reality star documented on Instagram, Richards stayed mum on her illness.

To see all the drama between Kim Richards and Lisa Rinna play out, tune into The Real Housewives of Beverly Hills‘ fifth season when it premieres on Bravo on November 18.
