"After six seasons on Bravo's RHONY, I have decided to return to what I do best — journalism and producing," Radziwill told People in a statement.
"I am sure this does not come as a surprise to any of the viewers, all of whom have been supportive, encouraging, and kind," she added. "My original curiosity about reality television has waned over the years and I am focusing on TV and writing projects that better suit my more steady temperament. I have worked with amazing producers, made great friends, and I'm thrilled to leave frenemies behind," Radziwill wrote. "I will remember this entire experience with delight, humor, and a veracious accuracy. Next."
Radziwill is an Emmy and Peabody Award-winning journalist. She has also been in a feud with fellow Housewife Bethenny Frankel all season because her boyfriend Adam Kenworthy apparently told Frankel he wanted to be compensated for an appearance at a charity event she was putting on.
The Real Housewives of New York City airs airs Wednesdays at 9/8c on Bravo.
