While the extent of it is unknown, Betty Suarez is undergoing a makeover this season on Ugly Betty.

Now, TV Guide Magazine reports that veteran actress Lynn Redgrave will play a key role in this transformation.

Redgrave will guest star on the two-hour season premiere of the show, which airs on October 9. She'll portray Olivia, a jewelry designer that Betty - newly promoted to Mode's features editor - comes across while working on a story.

Olivia designs beautiful, bug-like baubles. In the course of relaying her story to Betty, she inspires the show's title character to come out of her shell and blossom in a new way.
