Will the iPhone 5 Lifeproof fit the iPhone 5s?

Will it?

I don't know this for certain, but I'm guessing that it will likely fit except possibly for the camera (the holes might not line up properly since Apple introduced a new dual-LED flash for the 5S). Otherwise, I'd guess it'll fit just fine, since it doesn't seem like Apple changed the dimensions of the phone and didn't move the controls/ports around, apart from the new flash.

Hope that helps!
