As “The Real Housewives of New York” approaches its Season 6 finale, we hear fur will fly — and so will a leg.

Sources say this season’s July 22 episode features an “epic” battle between the catty cast at Le Cirque that’s punctuated by Aviva Drescher removing her prosthetic leg and throwing it across the eatery.

“During a wild argument” among the cast, a source says, “Aviva yells, ‘What do you want from me? To crawl out of here?’ All the while, she’s shimmying out of her prosthetic leg under the table.” She then “throws it, in front of a crowd of shocked people.”

The incident happened last fall, but witnesses signed non-disclosure agreements and have largely kept quiet.

A Bravo promo for the current season teased the bizarre incident by showing an image of a detached gam in a high heel lying on the ground, but without revealing where the leg came from or how the incident happened.

Said a source of the leg-tossing melee, “It’s something that definitely has not been seen on TV before.”

Drescher lost the limb in a childhood accident and wrote about it in her book, “Leggy Blonde.”

Meanwhile, speculation’s swirling over which wives will be back next season. A spy says the whole cast is being let go “except Ramona Singer.” But another source close to Bravo says no decisions have been made and rumors are being spread by an ex-castmate who’s still sore about no longer being on the show.
