Pizza Delivery for Nicole Richie!

We'd never defend Paris Hilton. She's a drunk driving, immoral, spoiled wench of an ugly human being.

However, if the following story is at all valid, Paris does know how to pull a prank or two.

Word is circulating that Nicole Richie has been receiving certain, surprise treats in the form of pizza deliveries for weeks now. A prankster has been ordering the pies and having them delivered late at night to Lionel's frail step-daughter.

"The stunt has Paris written all over it," says one insider. "She can't stand Nicole and loves that her former best friend is being ridiculed by people for her appearance. Sending pizzas is the kind of thing (Paris would) think was funny."

We're pretty sure sending pizzas is the sort of thing anyone would think was funny. Except Peter Sarsgaard, perhaps. He takes stuff like this really seriously.
