The star gathered a few of her closest friends, including actresses Adrienne Janic and Jennifer Gimenez, and realtor boyfriend JR Ruiz, for dinner at Fleming's steakhouse in Beverly Hills, a source told E! Online.
None of Glanville's "Housewives" co-stars attended the celebration, though "Yolanda [Foster] was supposed to come but at the last minute didn't make it," the source said.
Despite a recent tiff between Glanville and Foster, in which the birthday girl accused Foster's ex-husband of having an affair with "Real Housewives of Miami" cast member Joanna Krupa, the source said the two are "fine again."
"They worked it out and things between them are good."
The dinner included a seafood tower, lobster tempura -- Glanville's favorite -- steak and salad, as well as a variety of desserts.
