Gretchen Rossi, formerly of "The Real Housewives of Orange County," teamed up with former "Real Housewives of Beverly Hills" star Joyce Giraud and "Vanderpump Rules" star scheana marie to support the victims of the Puerto Rico hurricanes over the weekend. According to a new tweet from Mykesha A. Robinson, the women were in attendance at a holiday-themed event thrown by celebrity stylist Pol Atteu.

According to Pol Atteu's Facebook page, the event was titled Presents for Puerto Rico and was a huge success. In addition to sharing a number of images of himself and partner Patrik Simpson, Atteu posted images and a video clip of himself and Giraud posing with Santa at the event.

Gretchen Rossi is just one of Pol Atteu's "Real Housewife" friends. As fans may know, the estranged brother of "The Real Housewives of Orange County" cast member Peggy Sulahian is also close with Lisa Vandepump of the Beverly Hills-based franchise, and former "Real Housewife" Adrienne Maloof, also of Beverly Hills.

Joyce Giraud is from Puerto Rico

In a flyer for Pol Atteu's event, Joyce Giraud was listed as a host alongside him and it appears to be quite clear why. After all, in addition to growing up in Puerto Rico, Giraud was once named Miss Puerto Rico and came in as the second runner-up while representing the country in the Miss Universe pageant in 1994.

As fans of "The Real Housewives of Beverly Hills" may recall, Giraud was brought to the cast of the Bravo TV reality series during its fourth season, along with Carlton Gebbia, to replace Adrienne Maloof and Taylor Armstrong, who both left the show after season three.

Then, ahead of the show's fifth season, both Giraud and Gebbia left their full-time roles and were replaced by Lisa Rinna and Eileen Davidson.

Gretchen Rossi was added to the cast of "The Real Housewives of Orange County" during its fourth season and continued to star on the show in a full-time role until the series' eighth season -- after she proposed to fiance Slade Smiley on top of the AT&T building in Los Angeles. Since then, Rossi has continued to spend time with her former co-stars, including Vicki Gunvalson [VIDEO], and recently returned to the show in a guest role. As for a potential full-time return to the Bravo TV reality series, rumors have been linking Rossi to the show for some time, but so far, nothing has been confirmed.
