The Real Housewives of Atlanta star Kim Zolciak is the latest celebrity posing — topless, might we add — for the NOH8 Campaign, a marriage equality campaign protesting Proposition 8, California’s constitutional ban against same-sex unions.

“the noh8 campaign shoot was hot. and I am topless!!! Just to cause a stir to make people pay attention!” the “Tardy for the Party” singer Tweeted Tuesday.

Pete and Ashlee Simpson-Wentz, Aubrey O’Day, and Isaiah Washington have also posed for the campaign.
