Sorry, pkmac, but I hate Heidi! And I think she'll walk before too long. It seemed to me as if she didn't really get it, didn't know why she was there and, frankly, looked a bit out of it. I'd bet money that she'll walk.
I like Stephanie, but I'm not sure about the rest of them. I always end up getting sucked in, though, and I'm sure this year won't be any different! I love BB!
