The 24-year-old singer believes the demands of motherhood affect an artist's creativity in a negative way and at the moment all she wants to do is focus on her music career.
She said in an interview with Rolling Stone magazine: "I'm terrified of babies. I think, creatively, as a woman, you change once you give birth. I'm totally not ready for that."
The eccentric singer also spoke about the love she still has for an ex-boyfriend, who she refers to only as a heavy metal drummer called Luke. Gaga credits him with helping her become the pop megastar she is today.
She explained: "I wouldn't have been as successful without him. I've never really loved anyone like I loved him. Or like I love him. That relationship really shaped me. It made me into a fighter."
"But I don't want to talk about him... he's too precious to talk about."
Although she has been in love before, the "Alejandro" singer doesn't think she understands the complexities of the heart.
She said: "But, you know, I don't really know much about love. I suppose if I knew everything about love, I wouldn't be good at making music, would I?"
