"The Hills' " Spencer Pratt and sis Stephanie Pratt: Who's more evil?

If you hate Spencer Pratt, you'll just loathe his younger sister, Stephanie Pratt.

That's what fellow cast member Brody Jenner says. "She's a million times worse!" Jenner told Us.

In a new trailer for Season 4 of "The Hills," Stephanie, 21,  is seen having a romantic candlelit dinner with Lauren Conrad's baseball player boyfriend, Doug Reinhardt. Why, that little backstabber.

Natch, Stephanie denies. "He was giving me boy advice," she told E!

But Jenner says no way. "He might not have known that it was a date, but she had candles, and they were alone!" Jenner said. "It was a date."

Who do you hate more, Spencer or Stephanie? Tell us.

Hard to pick isn't it?
