'The Real Housewives of New York City' are Back -- And Some New Ones, Too!

Ramona Singer, LuAnn de Lesseps and Sonja Morgan returned to the show, along with newbies Heather Thomson, Carole Radziwill and Aviva Drescher. It didn't take long for the fireworks to begin.

As for the new faces, Thomson is the creator of "Yummie by Heather Thomson," a popular and innovative shapewear line, who is also married mother of two.

Radziwill is an author and journalist, who has worked for ABC News. Her first book, “What Remains: A Memoir of Fate, Friendship and Love,” is a moving account of her life and marriage to fellow ABC News producer Anthony Radziwill -- the only son of Lee Radziwill, Jackie Kennedy Onassis' sister. Anthony died in 1999 after a five-year battle with cancer.

Drescher is full-time mother of four, devoting her time to her children and investment banker husband. She suffered an accident as a child and lost her leg, and now wears a prosthetic limb, which has lead her to spend time working for amputee organizations such as One Step Ahead, along with other charitable works.
