Garrett, who has worked with the likes of Britney Spears, Destiny's Child and Usher, has told The Daily Star that he's been in the studio creating a "mish-mash of genres" with Guetta for the Bajan babe's seventh studio LP.
He explained to the newspaper: "I was in the studio with David doing some stuff for Rihanna recently.
"He finds inspiration in the things I don't like, and I get excited by the things he doesn't like. He wants to be more urban and I want to be more international, so we push each other."
Garrett went on to state that their work together is "a great mish-mash of genres", adding: "I try to help Rihanna. She works hard and it's cool to write for someone who is so open-minded."
The 24-year old singer has previously worked with Guetta on track Who's That Chick, which reached the UK singles chart top ten back in November 2010.
UK talents Labrinth and N-Dubz star Fazer are also said to be in line to contribute to RiRi's forthcoming record, with Lab recently telling Capital FM: "She's not in my studio [yet] but hopefully I'll have some hot ones on her album."
