Could one of Lisa Vanderpump's friends be joining the cast of The Real Housewives of Beverly Hills for season six?

According to a new tweet, fans may be seeing Joyce Giraud, who starred on the Bravo reality series' fourth season, on the next installment. Shortly after Vanderpump confirmed filming on season six began, she spoke to Giraud on Twitter.

Giraud was brought aboard The Real Housewives of Beverly Hills cast for season four, but released from her contract ahead of season five. Still, fans may not have seen the last of her.

Although Bravo has yet to make an official announcement in regard to the season six cast, Giraud has spoke of a return on more than one occassion, and each time, Vanderpump appeared to be on board with the idea, which could certainly work in Giraud's favor.

In recent weeks, Vanderpump and Giraud seem to be growing closer, and with season six filming under way, it wouldn't be surprising to see Giraud appear -- especially since the show is in need of a couple of new wives, following the elimination of the full-time roles of Brandi Glanville and Kim Richards.

The Real Housewives of Beverly Hills season six began filming last week in Los Angeles and is expected to premiere on Bravo later this year.
