Lady Gaga's former DJ, Brendan Sullivan, sold his memoir, "Texts, Drugs & Rock 'n' Roll," to HarperCollins imprint It Books.

Sullivan was an up-and-coming New York City DJ when he met Lady Gaga, then a struggling performer, in 2006.

The book, out next spring, is described as "a literary memoir about love and heartbreak in the downtown New York music scene during the rise of Lady Gaga."

HOT SHOTS: Lady Gaga

"My book will include six or seven people who either want to be Gaga or want what Gaga did," Sullivan said. "Fashion designers, young chefs, kids who are bartending on the weekends to make their dreams come true. The book is about what it's like when you are in that position."

HarperCollins is owned by News Corp., the parent company of the New York Post and NewsCore.
