Jill Zarin, Alex McCord, Kelly Bensimon and Cindy Barshop are out – but who are the brave new stars of The Real Housewives of New York City that will join Ramona Singer, Sonja Morgan and LuAnn DeLesseps in upcoming seasons of Bravo’s hit show?

A source close to the show tells PEOPLE that New York City is in need of “new energy,” and heard that the new cast will include a woman in the fashion business, a philanthropist with three children and a writer.

Well, a report in New York’s Daily News names three women who fit that bill.

Best-selling author and former ABC News producer Carole Radziwill, whose late husband’s aunt was Jacqueline Kennedy Onassis, is joining the reality show, according to the report. Radziwill was friends with Carolyn Bessette-Kennedy, who died alongside her husband John F. Kennedy Jr., when his plane crashed in 1999.

Fashion designer Heather Thomson, who has two kids and a shapewear line (ouch, Jill!) called Yummie Tummie, will reportedly join Radziwill and “Wall Street wife” Aviva Drescher, a mom of three, as cast newbies.

A rep for Bravo says the network, which airs The Real Housewives of New York City, has not made any announcements about new ladies yet.
