The 39-year-old, who is seven months' pregnant with her and Hoppy's first child, has been tweeting about her pending nuptials throughout the week. She wrote on March 25: "I'm getting married in 2 days and housing a pint of ice cream. No need for flat belly at this wedding!"
The natural foods chef and The New York Times best-selling author has starred on Housewives for three years. Bravo cameras will capture the wedding for her upcoming spin-off, Bethenny's Getting Married, which is set to debut sometime this summer.
Frankel and Hoppy met in November 2008 and have been engaged since last October.
