All's well that ends well.

Jill Zarin's friendship with Bethenny Frankel went down in flames on the last season of Real Housewives of New York.

What's the group dynamic nowadays -- with newcomer Cindy Barshop in and Frankel out?

The fourth season (premiering April 7) is "my favorite," Zarin told during a visit to the NYC headquarters with her sister, radio personality Lisa Wexler.

"Living through it was the most enjoyable season," Zarin. (Frankel now stars in her own Bravo series, Bethenny Ever After; waxing salon entrepreneur Barshop joins show vets Zarin, Sonja Morgan, Luann de Lesseps, Kelly Bensimon, Ramona Singer and Alex McCord.)

"I don't think Bethenny ever really fit into the group," Zarin tells Us. "She's found herself on her own show -- her own island. She self-admittedly doesn't like people [besides her husband Jason Hoppy and daughter Bryn, 10 months.]."

In the clip, Zarin and Wexler, talk about a new paperback edition of Secrets of a Jewish Mother, which they co-authored with their mother Gloria Kamen.

"Jill was really bullied as a kid," Wexler tells Us, adding that she had a "duel" at summer camp with a particular mean girl.
