Jesus Take the Wheel: What is Nicki Trying to Do?

I don't know what's going on right there, but i just need an explanation on the stunt Nicki Minaj & Cassie are trying to pull. Even if with Nicki new things come up every now and then but with Cassie? That's some crazy move right there.
Got this caption from her (Cassie) coming video for the "The Boys" featuring Nicki Minaj. I don't know, I mean maybe they are trying to reveal their girlly thing out there but i think it would have been better if they tell us straight. Or what do you think?
