Grammer appeared on The Real Housewives of Beverly Hills during seasons one and two as a full-time cast member, or official housewife. After the second season wrapped, Grammer quit the series, but ultimately returned for season three in a recurring role. 

On season four, Grammer wasn't seen at all. Instead, she and Adrienne Maloof, who also left after season three, were replaced by Carlton Gebbia and Joyce Giraud, who both lasted just one season before getting the boot.

After Grammer and Maloof attended Kyle Richards' Annual White Party, which was seen in one of the first episodes of The Real Housewives of Beverly Hills season five, a source confirmed to PEOPLE Magazine that while they had returned to the series briefly, the network had no plans to upgrade either of them to a full-time role.

The Real Housewives of Beverly Hills airs tonight at 9 p.m. on Bravo.
