It’s unclear if the pair struck a monetary settlement as part of the apparent peace deal, but Fusari had previously alleged he was denied a 20 percent share of her song royalties.

Friends of Gaga are quoted in the book saying Fusari took advantage of her and she eventually fell in love with him.

The couple has since broken up and Fusari has slapped Gaga with a $30.5 million lawsuit, claiming he gave her the name Lady Gaga and owns a 20 percent share of her career.

Also exposed in the book is the revelation that Gaga’s father Joe Germanotta is half-owner in her business.

Industry executives and lawyers interviewed in the biography say it is almost unheard of for an artist to share half their business with anyone and that Gaga often gets into arguments with her father over her frivolous spending.
