This is definitely the last season of ABC's Ugly Betty. Today, ABC and the production team made the following statement. At least fans will get their closure!
"We’ve mutually come to the difficult decision to make this Ugly Betty’s final season, and are announcing now as we want to allow the show ample time to write a satisfying conclusion. We are extremely proud of this groundbreaking series, and felt it was important to give the fans a proper farewell."
This is no surprise to anyone who has been following the ratings, but there was some question over whether ABC might want to squeeze additional episodes out of it for purposes of syndication. But, that question has now been answered.
