Remember Trista Rehn? She's the 29-year-old physical therapist who got rejected by Alex Michel on ABC's surprise hit The Bachelor. Well, it's Rehn's turn to do the rejecting: ABC announced today at the Television Critics Association press tour in Pasadena, Calif., that the Miami native has been selected to headline The Bachelorette. The six-episode series — which will follow the same format as The Bachelor except Rehn will humiliate 24 men until she finds that one special guy — will debut in January.
