Source: Bethenny Frankel’s Engagement Fake, Could Be Sued?

Bethenny Frankel’s professional life couldn’t be better with reports she has just landed her own spin-off reality show "The Skinny & the City" to apparently debut this fall (Bravo declined to comment), and personally things are looking pretty positive too with news she is engaged to "real estate bigwig" Jason Hoppy.

But could all the talk of dresses and diamonds actually be a PR stunt?

"The engagement is fake," said our inside snitch, adding that in "reality" Hoppy is a medical sales rep/personal trainer, not a "property guru."

In the United States, real estate licenses are issued by the state where a person does business. While Hoppy's address is in New York, Pop Tarts has learned that he is not licensed as a sales person or broker in NY.

A rep for Frankel did not respond for comment.

But Frankel's fiance's true profession may be the least of Frankel's worries. If her rumored new reality show does hit the airwaves, Frankel and her people could find themselves in a not-so-skinny legal situation.

Registered dietitian and author of "The F-Factor Diet" author Tanya Zuckerbrot also runs popular weight loss website www.skinnyandthecity.com, and is less-than-impressed with the name swipe.

"While I am obviously surprised by this news, I have always felt imitation is the sincerest form of flattery. That being said, we are taking the protection of our brand and trademark extremely seriously," Zuckerbrot told Tarts.

And according to insiders, HBO is very sensitive to any titles bearing even a passing resemblance to their own cult classic series "Sex & the City," something Sydney-based dating/relationships columnist Samantha Brett learned the hard way a couple of years ago. Pop Tarts has learned exclusively that Brett was forced to change the name of her "Sam and the City" column to "Ask Sam" www.smh.com.au/asksam and pull books with the same title off the shelves after her publication reached a settlement with HBO before the matter went to court.

A rep for HBO told Tarts that they will look into whether they will pursue legal action for copyright over the murmured "Skinny & the City" Bravo show, but as yet don’t have enough information.
