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.

Najimy is scheduled to appear on the March 24 episode, and in addition to performing dental work, she's also going to act as Betty's guardian angel in an 'It's a Wonderful Life'-style scenario, in which Betty gets to see how different things would have been if she had never gotten braces in the first place.

It sounds like a fun episode to wind down the final season, but it's going to be weird seeing Betty without her signature metal. What do you think? Are you excited about the makeover, or should Ms. Suarez stay the way she is?
