TINSELTOWN SPYWITNESS.

Byline: Elizabeth Snead

A 'LITTLE' BIT: ``You're as big as you feel'' was the theme of the day at the very-big-indeed Westwood premiere of ``Stuart Little 2,'' benefiting CuresNow, dedicated to find cures to diseases via stem cell research. The organization was founded by producers Jerry Zucker and Doug and Lucy Fisher, producers of the ``Little'' saga.

Their new film about the continuing adventures of the plucky pint-sized white mouse also featured a block long after-party with wild rides such as Ferris wheels, inflated slides, bright yellow tables covered with red rose centerpieces and endless tables of picnic food including salads, hamburgers, dogs, veggies and mouse-sized desserts. There were booths for Stuart Little tattoos and beadmaking, not to mention wandering mimes, jugglers, even some famous fine feathered friends, including the bright green parrot from ``Dragonfly'' and the falcon featured in ``The Scorpion King.''

A slightly frail but happy Michael J. Fox, the voice of Stuart, attended the film with his wife and kids but came late to the party after going back to the hotel to feed their new baby.

Jonathan Lipnicki came ready to party hearty, wearing a hip crew cut, a black mesh T-shirt and a pair of sequined Gucci cropped pants. His next gig will be a more serious role in ``When Zachary Beaver Came to Town.''

``I play a boy whose mother left him to become a country-western star, and he is lonely until he bonds with a 600-pound boy from a freak show that comes to town,`` Lipnicki says. ``It sounds funny, but it's pretty serious and definitely the heaviest role I've done yet.''

Other family oriented guests Jenna Boyd, Antonio Sabado Jr., Leeza Gibbons, Christopher Lloyd, Hans Zimmer, Heather Locklear and Richie Sambora. Lisa Rinna,, wearing tight white jeans with a camouflage print backpack, came with hubby Harry Hamlin, who shouldered one of their brood.

Director Rob Minkoff admitted that, while Stuart Little may be the film's beloved star, the character he would most want to hang out with would be the film's wisecracking Persian cat, Snowbell.

Melanie Griffith, the voice of Margalo, a sweet if slightly larcenous bird, admitted that she had a very hard time doing her very first voice over gig.

``It's so hard!'' the breathy voiced blonde exclaimed. ``It's much harder than being in front of the camera. I've been doing that for so many years I know how to work it, but when it's just your voice, it's really different. The first time I did it with Michael and afterwards Rob called me and said 'You suck and you have to get bigger and better.' I did but it was a lot of work.''

Geena Davis, who plays Stuart's overprotective mother, admitted that she's ``in the family'' for the next one and even the one after that.

``Stuart needs me! I'm his mommy.'' But after Stuart's crush on Margalo in ``Little 2,'' Davis is preparing to have a little talk with her son, who is fast approaching puberty. ``We may have to have a little talk about the birds and the bees,'' Davis says. ``Especially the birds!''

GEEZER-FREE ZONE: Kirsten Dunst has announced it to the world: no love scenes with older leading men.

Dunst, who had her first on-screen kiss with Brad Pitt when she was just 11 in ``Interview With the Vampire,'' turned down the role played by Mena Suvari in ``American Beauty'' because she didn't want to lock lips with Kevin Spacey, then 39.

Would the ``Spider-Man'' star smooch Pitt on screen again? She recently stated ``How old is Brad now - almost 40?'' (He's actually 38.) ``I'm sorry, but that's supporting something I don't believe in.''

Hel-lo? Strange talk from a gal who lives in Hollywood, where powerful older men always sport arm candy 20 to 30 years younger.
