Nicki appeared on Chelsea Handler's show Chelsea Lately yesterday where she talked about her famous behind and alter-egos.
She said she had three most popular alter-egos, Nicki, Barbie, and Roman Zolanski.
Minaj said: "I have Martha, who is Roman's mother.
"I made up a new one the other day called Rosa. Nicki is the regular accent girl. Southside, Jamaica, Queens."
The 26-year-old singer described Roman as the 'gay boy. He's very flamboyant and into himself.'
Host Chelsea, 35, wondered if it would work if she was dating one guy and they're dating another.
Nicki replied: "It does because we all like different types of boys, I don't like Roman's taste, he doesn't like my taste. It's weird like that, but we all agree that we like big..."
The Check It Out singer went on to say how she dislikes the double standards that are expected of women.
She said: "When you're assertive as a girl, you get called a 'bitch.' As a boy, he gets called a 'boss.' It's a double standard, Chelsea, I don't like it."
But there is one place she likes not to have to take control - behind closed doors.
She added: "I like for the boy to take control."
