After a five-year hiatus, Heather Dubrow makes her return to Season 16, joining veteran Housewives Shannon Storms Beador, Gina Kirschenheiter and Emily Simpson. The ladies are joined by Dr. Jen Armstrong, an aesthetic M.D. who immediately integrates into the group by performing cosmetic procedures on the ladies, and Noella Bergener, whose world is turned upside down when her husband unexpectedly files for divorce.
