We're not sure what Kimberly Stewart had more of at London's Heathrow Airport yesterday: expensive luggage or bitterness at the world.

The daughter of Rod Stewart, who may be more useless than Nicole Richie (at least she leaves extra food for people), sported a pair of vintage, vicious boots as she strolled to her chafeur-driven ride. You can see their delightful message for yourself in this picture.

Rod must be as proud of Kimberly as Mel Gibson is of Michael Richards.
