The 'Real Housewives of New York' star is suing the manager of her Yummie brand.
Real Housewives of New York star Heather Thomson is breaking her silence on the major lawsuit surrounding her fashion brand, Yummie.
"It’s an unfortunate distraction," Thomson told ET exclusively. "I’m hoping for a positive result in a very short time so I can get back to focusing on what’s important: the business of my ever-expanding Yummie brand."

Thomson is suing the manager of her brand, Eric Rothfeld, claiming that Rothfeld hurt the brand by not allowing RHONY cameras to film in the Yummie building. Thomson and her team are also attempting to replace Rothfeld as the brand’s manager, a process made more difficult by the fact that Rothfeld is also a part-owner.
In an email submitted with the court filing, Rothfeld is seen instructing employees not to allow any connection between Yummie and RHONY.
"Effective immediately, under no circumstances are you to spend any time discussing or working with Heather on Rhony [sic]," Rothfeld wrote. "No samples should be provided to Heather for Rhony and Rhony is not authorized to film in our offices. Also, there is to be no Company money to be spent for Rhony."
A motions hearing is set in the case for Oct. 30.

Thomson spoke to ET in September about leaving the reality show after three years, citing her obligation to Yummie as a major factor in her decision.
"The reality of it that I just can't do it anymore," she admitted. "I have to focus on the things that are really, really important in my life and that's my family and my business. While I'm filming the show I also am running a multi-million dollar business, and it takes away a lot of my time from the company."
