Corinne hatch is Brittany. She has changed her networking name, probably to distance herself from ANTM. That's what it says when you search Corinne Hatch.
She was eliminated because they assumed that she wouldn't book a job. But all I see here is that she does book a lot of job and takes beautiful pictures! Well, maybe in the real-reality she isn't that annoying. IMO.
For anyone who doubts that Corrine and Brittany are the same person, look at this shot then her shot from her men's magazine shot from the show and tell me they aren't the same person. The face is so similar in both photos.
