Last night Real Housewives of the past and present sashayed and twirled down the red carpet at OK! Magazine's pre-grammy party in L.A.

Joanna Krupa stole the spotlight in this sheer and black gown that reminded of us the revealing dress that Paris Hilton wore the night before to Diddy's own pre-grammy party. (see below). Almost all of the ladies of Bravo (and a few VH1 stragglers) wore black, except for Real Housewives of Atlanta's Kenya Moore, who opted for a purple number. Last night was also Kenya's birthday and we'd be willing to bet her evening included a little birthday toast over the news of Apollo Nida's criminal charges.

Also in attendance: former Real Housewives of Orange County star Gretchen Rossi, Real Housewives of Beverly Hills stars Kyle Richards and Joyce Giraud (whose husbands may be hanging out too often, as they're starting to dress alike), and Couples Therapy star Farrah Abraham. Also on the carpet: NeNe Leakes and Laura Govan, as well as some of the cast of Vanderpump Rules: Scheana Marie, Katie Maloney, Kristen Doute and others.

Updated to add new pis of Slade Smiley, Lilly Ghalichi, Jax Taylor and more!
