'Real Housewives of New York' Season 5: Ramona, LuAnn And Sonja Approve Of Newbies (VIDEO)

"Real Housewives of New York City" is back for a fifth season of reality TV drama and the cast is full of new faces.

"Real Housewives" veterans Sonja Morgan, Roman Singer and LuAnn de Lesseps stopped by "Good Morning America" (weekdays, 7 a.m. ET on ABC) to talk about their new Bravo cast members Aviva Drescher, Carole Radziwill and Heather Thomson.

"You either sink or swim when you come on, and these girls are swimming," Sonja told Lara Spencer.

The new faces were brought on after Jill Zarin, Cindy Barshop, Kelly Bensimon and Alex McCord were given the boot from the series following Season 4.

"The dynamics are incredible this season," Ramona said.

In an interview with The Huffington Post, Aviva said the three veterans were welcoming. "There's definitely a lot of drama and you're definitely going to have to wait and see for all the drama, but I would say there was a warm welcome from all the oldies," she explained.

"Real Housewives of New York City" returns Mon., June 4 at 9 p.m. ET on Bravo.
