"Real Housewives of Beverly Hills" -- Secret New Castmember REVEALED at LAX


The rumors have been swirling for months ... but TMZ finally has the video proof that former 2-time Miss Puerto Rico winner Joyce Giraud has joined the "Real Housewives of Beverly Hills."

Giraud -- along with Lisa & Ken Vanderpump, Kyle & Kim Richards, Brandi Glanville and Yolanda Foster were all at LAX this week ... waiting to board a flight to Puerto Rico.

Giraud tried to lay low ... in what appeared to be an effort to go unrecognized ... but our photog was quick to notice the beauty queen.

As for the other woman rumored to be joining the cast -- '90s actress Carlton Gebbia -- she wasn't at the airport, but sources tell TMZ she will appear on the show this season in a small role.

Taylor Armstrong was also M.I.A. at the airport -- we're told she's been spending a lot of time with her BF in Vail, CO -- but "Housewives" sources tell us she's also expected to make a small appearance on the show during the upcoming season.
