On second thought, since it’s Park Slope, it probably is:

Two exes each own a pastry shop: one is the shop they built together, Delices de Paris, and the other is the just-opened patisserie on Seventh Avenue that will be called Zana Café.

Owner Rosana Rosa opened the cute shop without her ex-husband, Michael Martin — with whom she opened Delices de Paris during happier times six years ago.

At her new joint, she sells French-Italian pastries and European products — just like Delices de Paris. And her walls are painted happy yellow — just like Delices de Paris.

No wonder Martin hung a sign in his front window (inset) telling his customers that he has nothing to do with his ex’s new shop — despite how much it looks like Delices de Paris.

“They are completely different products,” he said. “She used the same [paint] to mislead the customers and make them think that the two shops are related.”

. . .

Rosa also said she has nothing to be ashamed of: “I built Delices de Paris with my own hands. When we began, there was no place in Park Slope to get a chocolate croissant, now you have Colson Patisserie on Sixth Avenue and everyone is doing the French thing.”

What about her ex-husband’s sign on his door?

“Well you know divorce is tough, it is complicated,” she explained. “Some people never get over it.”
