For the singer-rapper, partnering with Ross has long been in the works.

Fergie recalls, laughing.

In the clip, the singer toys with duality.

“So if I’m wearing a pink bodysuit, then I’m in a very boyish stance.

This serves a larger purpose.

In Minaj, Fergie says she found an equal.

“She’s just as detailed as I am,” Fergie explains.

“I like when people are like that, because I can understand that.

I can’t see something that’s unfinished and be okay putting it out.

I don’t want to put out ‘okay’ stuff.”

“This is about us standing together as #Girlbosses,” she says.

“We have both worked very hard for what we have, and still continue to do so.

I’m a fighter!

And so is she!

We have the same goal.

I’m all about women not being pitted against each other.

I’m about, ‘Let’s stand strong.'”

Double Duchessis due out Sept. 22.
