This may be the last straw for Real Housewives of New York stars Bethenny Frankel and Sonja Morgan.

In light of recent litigation by Morgan’s new liquor line Tipsy Girl against Frankel and her Skinnygirl brand, a source close to the situation tells PEOPLE that claims made by Morgan’s business partner are exaggerated.

The source says that Peter Guimaraes’ statements to Page Six that Frankel wants to prevent he and Morgan from moving forward with Tipsy Girl is merely an attempt to drum up publicity.

Frankel, 45, believes the pair are attempting to “use [The Real Housewives of New York City] to have a fake story,” the source says.

Page Six reported that Skinnygirl filed court documents to trademark “Tipsygirl,” a move Guimaraes called “underhanded.”

“[Frankel] is threatened by this Tipsy Girl brand, which is not a copycat nor competition for Skinnygirl,” he wrote to the newspaper. “We are not advocating that you will lose weight with our product.”

The source tells PEOPLE, however, that Frankel “doesn’t care” about the line and is more concerned about Guimaraes and Morgan using her brand for media attention.

“This claim is not legitimate,” the source says of Guimaraes recent comments. “He attempted to register the name ‘Tipsy Girl’ for the restaurant, and his application was rejected because he sent in a picture of the bottle with a fake ‘Tipsy Girl’ label.”

The source says that the government bureau that oversees the alcohol and tobacco industries “would never approve the name ‘Tipsy Girl.’ ”

“This guy is trying to get his name in print,” the source adds. “It will never happen. Skinnygirl is simply protecting its intellectual property and making sure consumers are not confused.”

Frankel has a “legitimate” business that the Bravo reality show features a lot, unlike some of the other Housewives, the source says.

“These other people’s businesses are not always real,” the source says. “They have to find stuff to keep the others relevant.”

Guimaraes told Page Six that Tipsy Girl’s current prosecco product is awaiting distribution in warehouses and that he has “retained an attorney to handle Miss Frankel’s sneaky and illegal move.”
