Kathy Najimy, who has recently appeared on 'Desperate Housewives' as Susan's high school enemy, is set to make a guest appearance on 'Ugly Betty.' What's interesting isn't that she's going to be there, it's why she's going to be there. Betty's finally getting the braces off!

Najimy plays Betty's orthodontist and the one responsible for getting all of that metal out of her mouth. I guess Betty decided to switch orthodontists rather than have to deal with the creepy advances of her old one, played by 'Modern Family''s Jesse Tyler Ferguson.
