You will need your key ID for this.  For instance, my key ID is
0xD6B98E10.  Substitute your own key ID for mine in these instructions.

gpg --edit-key 0xD6B98E10 adduid

Enter the name, email address and comment you want associated with the
key; follow the prompts.  It's pretty straightforward.  Once you have it
done, send it to the keyservers so that everyone can find your key under
your new email address:

gpg --keyserver x-hkp:// --send-key 0xD6B98E10

Presto, done.
