The 30-year-old singer is currently working on the book titled, "Joanne Trattoria Cookbook: Classic Recipes and Scenes from an Italian American Restaurant," inspired by their family restaurant in New York, reported Entertainment Weekly.
Germanotta has ensured that his restaurant will not have Gaga's pictures on the walls but the cookbook will feature a foreword from the "Poker Face" hitmaker.
"Family, food, and love are the foundation upon which Joe Germanotta and his wife, Cynthia, raised their daughters, Natali and Stefani (aka Lady Gaga).
"Named for his sister who died of Lupus three months shy of her 20th birthday, their family-run restaurant is built on those same fundamental principles. In the pages of this cookbook, Joe has collected recipes and entertaining anecdotes inspired by his world famous restaurant," reads the description from the book's publishing company.
