We're officially entering fall in the hair world. How do we know? 'Tis the season of sleek bobs.

Kelly Ripa debuted her new 'do on "Live With Kelly and Michael" Tuesday, pleasantly surprising the audience with a more streamlined, edgy style to usher in the new season of the show. "Back in the saddle........with a new cut!" she tweeted.
