Nicki Minaj is arguably the biggest female in hip-hop, but the 28-year-old admits that just a few years ago, she felt completely worthless.

"I kept having doors slammed in my face," Minaj tells the November issue of Cosmopolitan. "I felt like nothing was working. I had moved out on my own, and here I was thinking I'd have to go home."

Things got so bleak that Minaj contemplated suicide.

"It was just one dead end after another. At one point, I was, like, 'What would happen if I just didn't wake up?' That's how I felt. Like, 'Maybe I should just take my life?'"

With her dark days now behind her, Minaj (real name: Onika Tanya Maraj) predicts her star will only become brighter with time.

"I will have put out five albums and will have an Oscar and Grammys," she says. "And I will be getting married and, a couple of years after that, will have a bun in the oven. My whole life is about being Nicki Minaj now. It's a never-ending saga."
