We first fell in love with Rose Byrne in the super-serious Damages, but we've come to appreciate her amazing comedic chops in movies like Bridesmaids and Neighbors.

Now she's hitting our funny bone again in Spy, as McCarthy's deadly serious nemesis, Raina.

Speaking with PrideSource's Chris Azzorpardi, Byrne revealed a rather familiar inspiration for her over-the-top diva character.

You really know how to play up the diva role. As an actress, where do you go, and who or what do you riff on, to achieve ultimate divadom?

You know, probably RuPaul or someone fabulous like that. That's a great diva! Or someone like Dame Edna Everage - she's a fantastic drag character by Barry Humphries, an Australian comedian/actor.

I know lots of queens who'd kill for your Raina hair in this movie. Who was your drag queen consultant?

(Laughs) I'm very honored and flattered you say that. As long as I have their approval, I'm done! (The studio) didn't actually want my hair like that. [Director] Paul [Feig] and I really had to fight for it.

We had a specific idea of where she was from and what she looked like - a lot of money, no taste, and very Eastern European. Very Marie Antoinette. But it's a spy film, so style is such an important element of it—even if it's bad style!

I'm glad everyone could agree that bigger is better in this case. How did you convince the studio to see it your way?

Once it was all together and we were on camera. It just all came together: the costume, the makeup, everything. And it just needed a little more. She's quite still as a character, and I think (the hair)... it says a lot! (Laughs) It was the stronger choice! That's how we convinced them.
