Big Changes In The Big Apple! Aviva Drescher Won’t Return To Real Housewives of New York City, Ramona Singer’s Camera Time Slashed & LuAnn De Lesseps In The Catbird Seat — As Radar Told You First!

Aviva Drescher is leaving The Real Housewives of New York for Marriage Boot Camp, which RadarOnline.com told you first, as the Bravo franchise streamlines its’ roster two weeks before it begins filming the show’s seventh season.

According to the NY Daily News, Drescher, who famously tossed her prosthetic leg at castmate Heather Thomson on the show last season, is slated to spend six weeks in Los Angeles to film the show with her husband Reid.

A source told the paper that the $150,000 the duo will receive to appear on Marriage Boot Camp is “a good paycheck for easy work,” and a smart pick-up for the program, as Aviva “knows how to create good reality TV.”

In another item RadarOnline.com brought you first, the paper reports that cast member Ramona Singer’s screen time will be drastically reduced, as the newly-split wine maven will appear in a part-time capacity on the Bravo program, documenting her single life.

One housewife who’s staying put is the Countess LuAnn De Lesseps, who was so coveted by the show’s producers, they pleaded with her to return, an insider told the paper.

“LuAnn was genius about it,” the paper’s source said, noting that the shrewd socialite “never complained about” the ever-present drama swirling around the show and it’s cast, opting to let it “fall apart without her.

As RadarOnline.com told you, the beauty was willing to appear on the show at the right price — i.e. free! — while shake-ups were in the offing.

“People love LuAnn — she’s happy to be back.”

Sonja Morgan’s French boyfriend Nicholas Brochet will have an enhanced on-camera presence as well this season, the insiders said.
