Finally I asked Lolo. I told her Christie is the spitting image of an actress, probably on Degrassi or some MTV show or something. I can see the actress plain as day in my head, but cannot place her. GAH. I also sent Lolo a Christie clip from Big Brother.
Lauren: It's Lauren Collins from Degrassi.
YEEEEEEEEESSS!!
So if anyone out there happened to be wondering the same thing... there ya' go.
