Radar Online reported today that Vanderpump has taken old friend Rinna under her wing. The website reveals that when Vanderpump got a star on the Palm Springs Walk of Fame, Rinna along with her husband Harry Hamlin and friend Lance Bass were there to support the restaurateur. No other Real Housewives of Beverly Hills cast members were present for the ceremony.

"Lisa Vanderpump is going out of her way to make sure that she can count on Lisa Rinna this season," a source told the website. "Last year, Lisa V. was left out in the cold as all of the ladies turned on her." Vanderpump has admitted in the past Season 4 was very rough for her and she almost didn't come back to the show.

"Both of them have been social acquaintances for years, but Vanderpump is truly going the extra mile to welcome Lisa R. to the show," the source continued.

Vanderpump tweeted yesterday without mentioning Rinna by name, "Enormous thank you, to all of you who came out to support me in Palm Springs, so grateful."

Rinna couldn't confirm when asked this week about being on the show, but did say to Us Weekly that she knew all of the ladies on it. "I do [watch the show] and I do know all the women," Rinna said. "I can tell you that [I've known them] for years."

Real Housewives of Beverly Hills is expected back on Bravo in the fall.
