Lady Gaga Talks About The Heartbreak That 'Shaped' Her Success

'I wouldn't have been as successful without him,' she tells Rolling Stone of onetime love Luke.

Lady Gaga strikes a formidable pose on the cover of the upcoming issue of Rolling Stone — wearing little more than a thong and a pair of M-16 assault rifles on her chest — but inside the magazine, she reveals that she's just as vulnerable as you or I, fueled creatively by a former boyfriend who broke her heart years ago.

In the new issue (which hits newsstands Friday), Gaga told writer Neil Strauss that she wouldn't have become the international star she is today if she hadn't gone through her breakup with a former flame named Luke, a heavy-metal drummer who has inspired everything she's done since.

"I wouldn't have been as successful without him. I've never really loved anyone like I loved him. Or like I love him," Gaga said. "That relationship really shaped me. It made me into a fighter."

In the piece, Strauss wrote that, after breaking up with Luke, Gaga "promised herself she would never love again and would make him rue the day he doubted her." And, during their interview, he asked her if the love she used to direct toward men was now being channeled into her deeply loyal "little monsters."

"I wouldn't say that my love for my fans is equated to my attention for men. But I will say that love comes in many different forms," Gaga replied. "And I sort of resolved that if you can't have the guy of your dreams, there are other ways to give love."

Strauss continued to press Gaga for details about her ex, but she told him, "I don't want to talk about him ... he's too precious to talk about." Though, she did say one last thing about Luke and her past life, before she became Lady Gaga — and how, by the sound of things, she'll never be looking back ever again.

"[It was] love. But, you know, I don't really know much about love," she said. "I suppose if I knew everything about love, I wouldn't be good at making music, would I?"
