Web Hosting with Word Press ?

Currently I am hosting my two wordpress.org websites with Host Gator and paying them 60$ every 6 months.

I also pay wordpress 26$ for each of my websites per year for the .com names.

I’m wondering if Word Press hosts domains as well, that way I can just do all my billing through Word Press and I wouldn’t need Host Gator anymore.

Is this possible? Or is it easier and cheaper to just use Host Gator? Thanks
