Brandi Glanville Teases Of Season Five Drama On 'RHOBH'

During a cast party earlier this month, Glanville and Richards, who've had an on-and-off friendship since Glanville joined the series for season two, were allegedly involved in a physical altercation -- all while Bravo cameras rolled.

“Kyle and Kim [Richards, Kyle's sister] got into a huge fight at a party. Brandi saw what was happening and went over to make sure Kim was OK,” a source close to the series revealed to In Touch Weekly on Sept. 18. “Kyle then went after Brandi and started yelling and getting in her face. Kyle pushed Brandi and scratched her arm!”

Although the pair had been doing well for the past two seasons, their relationship has been plagued with drama. During season two, the pair engaged in a heated exchange after Glanville accused Richards' sister, Kim, of using drugs. Following the allegation, Richards and her sister were seen screaming at Glanville. Then, during season four, Glanville and Richards became friends and were even spotted together outside of filming.

Unfortunately, things appear to have taken a drastic turn.

This isn't the first fight Glanville has been accused of while filming season five.

Just last week, a report surfaced, claiming Glanville punched Richards' sister after Kim accused her of being a drunk. After the report hit the web, both Glanville and Kim Richards denied being involved in anything but a great friendship.

The Real Housewives of Beverly Hills season five returns to Bravo this fall.

Just one year ago, Richards claimed to Us Weekly that she and Glanville had gotten to a better place on the show.
