Yolanda Foster also came out to support Nicky, wearing a gorgeous cobalt blue dress.

And remember Camille Grammer? While she’s no longer an official cast member, it seems that the former RHOBH will make an appearance or two on the new season.

As for other reality TV shows about Beverly Hills, Dorothy Wang from #RichKids of Beverly Hills came, along with her pals Morgan Stewart and EJ Johnson.

At the end of the night, the Hilton sisters, their mom, Kathy, and their aunts Kyle and Kim Richards posed for this photo opp. Can’t wait to see it all go down on the show!
