The Grammy-nominated rapper is dating a man called Kenneth Petty and has hinted that they're planning to get married.
As well as music, the 36-year-old has appeared in several Hollywood films and has her own radio show.
She's not made it clear how many of her ventures she's retiring from or, even, if she's being serious.
After releasing a string of mixtapes in the 2000s, Nicki Minaj joined Drake on Lil Wayne's record label Young Money Entertainment.
Her debut album Pink Friday came out in 2010.
Mega-hits like Super Bass, Anaconda and Starships then established her as one of the world's biggest female rappers.
Her solo albums have sold millions - but her collaborations list is just as impressive: Ludacris, Usher, David Guetta, Madonna, Ariana Grande, Kanye West, Justin Bieber, and we could go on.
She's been nominated for 10 Grammys, won five MTV Video Music Awards and broken the record for the most Billboard Hot 100 entries by a solo female artist.
Away from music, her film appearances include The Other Woman and Ice Age: Continental Drift.
But in 2018 there were signs the wheels might be coming off the Minaj-machine.
