If you have a cpanel, go into Parked Domains and add the new domain you want.

Go into your registrar's settings, and change the nameservers to hostgator's.

Wala! You've setup a new domain.

Try adding a new Add-On domain in cPanel, this usually works. Or get HG to update your main account domain name.
