Did Gaga become Mother Monster because of a bad ex?

According to Page Six, the "Applause" singer's ex-boyfriend Lüc Carl is not happy about how their past relationship is portrayed. Carl is threatening to sue Brendan Jay Sullivan, Gaga's longtime friend and the author of "Rivington Was Ours," a book about the earliest days of the pop star's career on the Lower East Side.

Carl has apparently sent legal letters to Sullivan and HarperCollins expressing anger that he has been painted as the "villain" of Gaga's past in "Rivington Was Ours." In the recently released book, Sullivan, a DJ, says that Carl was an "inattentive and possessive" boyfriend who attempted to control where Gaga was allowed to work and who she could speak to. According to the book, Carl, a heavy-metal drummer and radio personality, was frequently chased by female fans while he and Gaga were dating and that she even dyed her naturally dark hair in an effort to retain his attention and affection because as she says, "he likes f--king a blonde." Sullivan also revealed to Page Six, “Gaga told me herself that Lüc told her early in her career, ‘I hope you fail ...’" but that the ill wishes ultimately led her to fight even harder for her dreams.

Last year, Carl spoke about his tumultuous relationship with Gaga, saying “I was f - - king miserable, and it wasn’t her fault," but it looks like he's not permitting someone else making the statements. Carl also noted last year that he resents that his own career has been overshadowed by his status as Gaga's ex, but that he still wished her all the best.
