"The rumors about me not being on Housewives are false. You're stuck with me," she wrote after reports that she would be leaving The Real Housewives midseason surfaced.
The Real Housewives of New York City's third season will premiere on March 4 -- with Frankel, LuAnn de Lesseps, Kelly Bensimon, Alex McCord, Ramona Singer and Jill Zarin all returning and Sonja Morgan and Jennifer Gilbert joining the show's cast.
Frankel got engaged to boyfriend Jason Hoppy -- whom she began dating in December 2008 -- in October and confirmed she is pregnant with her first child shortly afterward.
The couple plans to marry before the baby's birth but has not announced a wedding date yet.
