It's Dedra Whitt!
Dedra "D.D." Whitt is an old friend of Camille's, and she's appeared in various episodes in Real Housewives of Beverly Hills. The makeup artist apparently does all of Camille's makeup on the show! Now that Camille is "Friend of the Housewives", we may not see that much of D.D., who tweeted, "Dont think so :( RT @phillygrl77: @DedraWhitt Are you gonna be on this season of #RHOBH?? I hope so! :-)"
