I'm torn.
Before this series even started, I wanted Charlotte to win. I still do mostly. As vulgar and disgusting as she is, I think she is a nice, caring and endearing girl.
I love Carol though. I've wanted her to go in CBB for years now! And she hasn't disappointed.
Then there's Lauren, who out of the 3 I'd like to win the least, but Lauren is lovely and I wouldn't be disappointed if she won.
They are my top 3 anyway. Any of them winning, I would be happy.
