Rihanna, who recently unveiled a number of tracks on the LP, said that she collaborated with the Queens rapper on a song called 'Raining Men'.
She told Captial FM: "You know I worked with her before on Rated R and she was just writing me some really good ballads and I couldn't wait to work with her again and finally have her on my record.
"It's a really fun song. It's called ‘Raining Men’. No, nothing like the original. It's quite up-tempo but kind of quirky and funny."
Discussing Minaj's character, she said: "She has a great buzz and she has a 'thing' to her. She is a star and that's why people love her. She's also really entertaining with her visual as well as her lyrics and she has a great melody.
"I'm really amazed that she can write like that. [Nicki] not only raps but she can write songs too. It was really easy actually. We were going back on forth with the texts on how we were going to get to do it because we were in two different places and had two opposite schedules."
Loud is released in the UK on November 15.
