DO 'GOOD GIRLS' EAT MAC 'N' CHEESE? Can you count the number of Hollywood parties that serve macaroni and cheese, cheeseburgers, French fries soaked in ketchup and blackberry cobbler?

Hold up one finger.

Those were the Midwestern munchies eagerly scarfed up by Brad Pitt, Jennifer Aniston, Courtney Cox-Arquette, Lisa Kudrow, Jake Gyllenhaal, Tim Blake Nelson, John C. Reilly and Selma Blair at the party for Aniston's new black comedy ``The Good Girl,'' held last week at the Astra West lounge in West Hollywood's Pacific Design Center. ``Girl,'' a Sundance Film Festival hit (it's in some theaters now but opening wider in the next week), stars Aniston as a bored clerk at a small-town discount store who dreams of a more exciting life.

The movie's message? Be careful what you wish for - and never eat fresh-picked blackberries.

But not everyone at the party was hot for the hometown goodies. One abstainer was Claudia Schiffer, wearing a low-cut maternity peasant dress and standing with her film producer hubby Matthew Vaughn (son of ``The Man From U.N.C.L.E.'' Robert Vaughn), whose main claim to fame was being best man at Madonna and Guy Ritchie's wedding.

When the stunning German blonde was asked if she wanted some macaroni and cheese, she wrinkled her nose and shook her head. See, that's why supermodels make the big bucks. Willpower.

EASTWOOD INSURANCE: Dirty Harry is back. But in ``Blood Work,'' Clint Eastwood has heart. A brand-new heart.

Eastwood produced, directed and stars in the new crime thriller, based on the novel by Michael Connelly. It premiered last week on the Warner Bros. lot, and stars Jeff Daniels, Tina Lifford, Wanda De Jesus and Anjelica Huston were eager to sing their director's praises.

``Having Clint as my partner in every single scene was so exciting,'' said Lifford. ``Being with a man who knows what he's doing, if you know what I mean - well, there's nothing a woman likes better.''

Even Daniels, who plays Eastwood's slacker pal, raved. ``Working with Clint reminded me of how lucky I am.'' But he felt more than just lucky after Eastwood saved them from becoming road kill.

``We were driving in the desert on a two-lane highway. Clint's in the passenger seat. The cameraman's in the back seat, and he says, 'I can see myself in the side mirror - can you reach out and fix it?' So I do, and the car floats into the other lane. Suddenly a hand reaches over and grabs the wheel. It's Clint and he growls, 'That was close,' just as a huge semi truck swooshes by.''

At 72, Eastwood looks healthier than ever. But age may have mellowed him. Asked what he learned from this movie about a heart-transplant recipient, Eastwood didn't miss a beat. ``It taught me about the vulnerability of our mortality.''

After the film, guests including Jimmy Smits, Gene Simmons with longtime girlfriend Shannon Tweed, and Portia de Rossi wandered outside into a tented supper club atmosphere with suede modular seating, a buffet of fresh fish, grilled steaks, vegetables and salads and a soft jazz trio.

Eastwood chatted with well-wishers while nursing a glass of red wine. His wife, Dina Ruiz, in a long black gown, stood by his side. The couple met when she interviewed him for a Northern California TV station, so it's fitting that she has a cameo in the film as a TV reporter.

Eastwood also chatted with ``Blood Work'' author Connelly, a longtime Clint fan. ``Thirty years ago, I used to go see all of his cop movies, like 'Dirty Harry' and 'Magnum Force,' with my dad,'' Connelly admitted. ``He had a huge impact on the way I write, so to have him make the film and play Terrell McCaleb, a character he actually inspired, is fantastic.''

The two met five years ago after Eastwood read some of Connelly's book-in-progress. ``Everything he told me that day came true,'' Connelly says. ``He said he would make some changes to the story, and he did. He said I would not hear from him until he was ready to make the movie. It was four years before we spoke again.''

That's Eastwood. A man of few words. A man of his word.
