Stephanie Pratt Filming 'The Hills' in Malibu 9/3

The ever-diminishing younger sister of Spencer Pratt was all smiles in her two-piece bikini as she engaged in an afternoon of watersports in Malibu.
And while they shared the same beach, Stephanie is more than a little apprehensive about Kristin.
“She’s like a disease you can’t get rid of,” she says of her co-star in the recently-released teaser trailer. “She’s the girl who’s going to stab us all in the back, and she doesn’t care. … How can one person turn all of our lives upside down?”
