Newcomer Lisa Rinna may already have her fill of the never-ending feud in "The Real Housewives of Beverly Hills" season 5. 

In the recent episode of the hit Bravo show, Lisa and co-star Kim Richards had a heated argument while the ladies were on the way to Calgary to attend an event hosted by Yolanda Foster's husband. The misunderstanding happened when Lisa expressed her opinion about Kim's struggle with prescription meds addiction. The "RHOBH" original cast member did not appreciate the opinion of the new cast member. 

The two decided to set aside their differences, until another row erupted between the two during the next dinner that they attended in Amsterdam. The Amsterdam fight began when Kim threatened to talk about a secret involving Lisa's husband Harry Hamlin. 

When she heard this, the soap opera veteran shouted, "Don't you touch my husband!" 

In an exclusive interview with PEOPLE, Lisa claimed that she is extremely protective of her family. The daytime TV actress also claimed that "If you poke a hornet's nest, you are going to get stung." She was also heard in the most recent episode that aired Tuesday that she is seriously considering going home earlier than expected. 

However, Kim's sister and fellow RHOBH co-star Kyle Richards stopped her, saying "We're not going to let her ruin the night." 

Lisa also recently revealed that joining the Bravo reality show almost ended her 18-year marriage with Harry during her appearance on the "Live With Kelly and Michael" show. 

In the next episode of "The Real Housewives of Beverly Hills" season 5 titled "Amster-damn Slap," the feud between Lisa and Kim continues. This also sets a division to the group wherein several of the ladies side with Lisa while others side with Kim. 

"The Real Housewives of Beverly Hills" season 5 episode 17 airs March 10.
