'RHONY' Cast: See the Season 9 Portraits

Look who's back!

Original "Real Housewives of New York" star Jill Zarin has returned to the fold in the new trailer for Season 9, marking the first time she's been on the show since exiting back in Season 4.

While Zarin makes a brief appearance in the new sneak peek, most of the drama this year revolves around main housewives Bethenny Frankel, Sonja Morgan, LuAnn de Lesseps, Carole Radziwill, Dorina Medley and Ramona Singer. Joining them -- and replacing one-and-done "Housewife" Jules Wainstein -- is socialite/designer Tinsley Mortimer.

The preview teases more feuding over the Countess' new husband, Tom, and his alleged infidelity. "I think he's cheating on you," an emotional Bethenny tells LuAnn at one point.

The video also gives us a peek at Frankel 100% naked and one of Dorinda's infamous meltdowns.

Season 9 kicks off April 5 on Bravo.
