Ain't no party like an OC party, and when Gretchen Rossi sought out to celebrate her birthday, The Real Housewives of Orange County alum gathered up some familiar faces to help toast another year. Among the guests included were Vicki Gunvalson and Kelly Dodd, as well as fellow alums Lizzie Rovsek (who served as the night's party planner) and Peggy Tanous.

Judging by the smiles on every one's faces, Lizzie did a really incredible job putting the little evening together, which also celebrated Gretchen's longtime love, Slade Smiley. You see, the couple's birthdays are just two days apart.
