EXCLUSIVE: While 'Real Housewife' Jill Zarin told me (first!) that her new look has nothing to do with plastic surgery, other members of the 'NYC' cast tell me they don't believe it. How else, they argue, can you explain the reality star's remarkable transformation?

Zarin, 47, denies getting any work done -- "If I did, I would be the first to admit it," she told me -- but her critics aren't so convinced.

"I really don't know what to think." Ramona Singer tells me. "If you see her in the photos, her face looks different. Personally I like her other look better."
