The Starships will play the actress' opinionated assistant in Nick Cassavetes' upcoming film The Other Woman, and Minaj can't wait to share screen time with the Charlie's Angels beauty.
In a Twitter.com exchange with a fan on Monday (06May13), she was asked if she was excited to work with Diaz, to which she replied, "She's only the hottest person on the f**king planet!!!"
The star has since revealed that she has undergone her first costume fitting for the project - but it all still feels like a dream.
She tweets, "I just left my 1st Fitting for my 1st Movie and God is this really happening!??!?!"
Comedienne Leslie Mann, Nikolaj Coster-Waldau and Kate Upton also appear in the film, in which Diaz's character teams up with the wife of her boyfriend when she discovers he's married - and the two women plot revenge.
