Weird noise on Coaster Breaks Cruiser Bike

[YoungPup]

When I pedal, there's no noise, when I brake there's no noise, but when I stop pedaling, there's this noise:

I opened up the back hub and sprayed it with WD-40 and it already had a bunch of grease on it too.

Not a expert on this but it sounds like your clutch or brake is dragging. I would take it to a bike shop for repair.
WD 40 by the way is useless as a permanent lubricant. Hopefully someone will opine with a better answer for you.
