Lisa Vanderpump basically scoffs when Joyce Giraud brings up the hair drama on this week's Real Housewives of Beverly Hills. But Lisa is now saying that Joyce's issue was bigger than Lisa realized.

"There had been a couple of conversations regarding me that had taken place between Brandi, Yolanda, and Joyce," Lisa writes in her Bravo blog. "I barely knew Joyce and was mystified by her pulling me aside to explain the situation. I felt at the time she was creating a problem out of something so trivial," but "what she was trying to relay to me was actually more important than I gave it credit for."

Lisa explains why she blew off Joyce during their rooftop exchange. "Maybe I was wrong, but I had a strong allegiance to Brandi and Yolanda, and Joyce being somebody I barely knew and insinuating they were being less than loyal was a sentiment I preferred not to entertain," she writes.

"I live and learn," Lisa continues. "There was an inkling at Carlton's that maybe some that I trusted to defend me were in fact doing the exact opposite. Anyhow, I chose to brush off the negativity then, and I do so now."

It will be interesting to see if Lisa and Joyce become closer over the course of the season.
