During an interview with French radio station SkyRockFM on Monday, Diesel explained, "Iggy Azalea, I just worked with her (two weeks ago) - I guess you're the first person to know this - we cast her in Fast & Furious 7. She has a cameo in the movie."
It's not really a surprise. Earlier this month, "Fast & Furious" actress Michelle Rodriguez posted a photo of herself with Azalea on Instagram with the caption: "Was great working with you Iggy Azalea, love to see you in concert. You rock".
"Fast & Furious 7" will open in theaters in April, 2015.
Azalea recently filmed the music video "Black Widow" with British singer Rita Ora, who appeared briefly in "Fast & Furious 6."
