Erika Jayne blatantly lied to her co-stars on last night's The Real Housewives of Beverly Hills, but in her blog, she claims she's not a liar.

After a San Diego performance, Jayne sat down with the women of the cast, who asked the group who had told Yolanda Foster about a conversation regarding her children, Bella and Anwar Hadid, not having Lyme disease.

"Who the hell told Yolanda that somebody said that about her kids not having it? Who said it?" Eileen Davidson asked the women, as seen in the Bravo clip below.

"I didn't say it," Jayne alleged.

However, on last week's show, she and Foster were seen sitting on the beach, and during their conversation, Jayne spoke of a conversation between Lisa Vanderpump and Kyle Richards, which included a discussion about Foster's kids.

Following the episode, Jayne took to her blog, where she proclaimed, "I am not a p***y or a liar. I never said that Lisa Rinna was the one who said anything about Yolanda's children."

Unfortunately, that wasn't what was asked of her. The question presented by Davidson had nothing to do with Rinna. Instead, Davidson simply mentioned Rinna earlier in the scene because it was Rinna who wanted redemption after being blamed for spreading the gossip, when it was Jayne all along.

The Real Housewives of Beverly Hills season six airs Tuesdays at 9 p.m. on Bravo.
