A pair of new faces will be added to the mix when The Real Housewives of New York City strut back onto the small screen for a third season next year. Big Apple socialites Sonja Morgan and Jennifer Gilbert have joined the cast of the popular Bravo docu-comedy/drama, The New York Post reported Thursday.

Don’t worry — Countess LuAnn de Lesseps, Bethenny Frankel, Kelly Killoren Bensimon, Alex McCord, Ramona Singer, and Jill Zarin will all be back for social calls and on-screen catfights. Sonja and Jennifer will come aboard on a “recurring basis,” the networks says.

Sonja Morgan, a former model and friend to European royalty and fashion designers, is a single mother of a 9-year-old daughter named Morgan. Sonja “loves art, decorating, gardening, skiing and visiting France every chance she gets — be it for her charity work or just for pleasure,” according to a press release from Bravo.

And Jennifer Gilbert, a successful entrepreneur, has been married for seven years and has three children. She owns and runs Save the Date®, a corporate and social event planning company, and serves as the co-owner of PortaMEe, a baby carrier company. Jennifer was named Entrepreneur of the Year by Ernst & Young when she was 29. She is a graduate of the “Birthing of Giants” Program at MIT.

Her motto? “Why cook when you can cater?”

The Real Housewives of New York City, currently in production, will return to Bravo in 2010.
