Rinna, who starred in soaps, including Days Of Our Lives and Melrose Place, for years, recently joined The Real Housewives of Beverly Hills for the series' fifth season. After turning down a spot on the Bravo show for years, Rinna, who also starred in reality show, Harry Loves Lisa, with her husband Harry Hamlin, signed on to Bravo this past July.

Although Rinna already had relationships with many of the women, including the Richards sisters and Lisa Vanderpump, her chemistry with Brandi Glanville and Yolanda Foster has been less than stellar.

As for Karen, Rinna claims to know the story of her life. “Karen had a 3-year-old daughter when she passed away, so I feel like she really presented herself to us when the girls were just babies,” Rinna explained to her fans. “She’s a good ghost. A protective spirit that I’m grateful to share my home and family with.”
