"I've done Pilates for three days a week for the past 10 years," Glanville said. But, the Housewives star added, "for the past two months I've skipped it because I've been moving. So I feel super out of shape right now."

Glanville just signed on to continue on Real Housewives of Beverly Hills for Season 5. There were early reports that Glanville was jealous of new co-star Lisa Rinna. Radar reported that Glanville was in fact not happy about Rinna coming on the show due to her "perfect" family life. Rinna is married to actor Harry Hamlin. The website reported that it all started at Kyle Richards' white party.

"Lisa had a very good time at and thinks being a part of the show could be really fun," an insider told the website. "It appears that Lisa is getting along with many of the ladies, with the exception of Brandi and Yolanda Foster," the insider continued. "Brandi's problem with Lisa is that she is happily married, and has two beautiful daughters. According to Brandi, Lisa has the perfect life, and she is very jealous of that."

Glanville slammed that rumor on her Twitter account saying she actually liked Rinna very much.
