OK, then what I would do is go to your Godaddy account and get to the phpMyadmin panel. When you are there, have a look at the wp_user table and see if the home url and site url are both set to http://www.girlsonthego121.com
That's the only thing I can think of, but it doesn't make much sense.
You could also see if you've got some weird domain redirects set in your Godaddy panel and you could try giving Godaddy a call.
Hopefully it's just a setting in the database that's not quite right.
