Celebrity style expert Phillip Bloch shares some top teasers from Hollywood as the stars get ready for Sunday's Oscars.

Live from Los Angeles, we give you Bloch:

Here's a secret that has yet to be uncovered (and what's the point of a secret if you can't share it?): Academy Award-winning actress and director Barbra Streisand will be presenting the award for Best Director.

Could this be a sign that we will have a woman winner in the category? Rumor has it that's why Babs was called in to give out the award -- from one female director to another.

On the fashion front. the big question is who will Streisand be wearing? A dynamic dress from her longtime friend Donna Karan? The fashionista says no, not this time.

Apparently, Barbra is working with an LA-based designer. Who could it be? Kevin Hall? Bradley Bayou? My guess is a number from gorgeous gown god and HSN star, Randolph Duke.

We'll have to wait until Sunday night to know for sure, but my money is on Kathyrn Bigelow ["The Hurt Locker"] for Best Director and Randolph Duke for Streisand's dress..

In other Oscar preparation news, as the designer gowns start to flood into town so do the designers. Zac Posen is due to fly into town today and if I was a baggage handler going through his suitcases at LAX, I'd be sure to find couture galore.

And Nicole Miller has already hit the Hollywood high life and hosted a dinner party for 20 of her nearest and dearest (including me, of course) at the hip hop Hollywood spot Cecconi's.

After Nicole's dinner, we were off to a party at the Andaz for Best Documentary nominee "The Cove." The party was thrown by The Creative Coalition, known for its bi-partisan celebrity fund raising events and its marches through Senate and Congress in Washington, D.C., lobbying to increase funding for the arts.

This posse and party was led by the one and only politico commander-in-chief Robin Bronk, who recently produced a documentary called "Poliwood" with famed director Barry Levinson.

The film follows countless celebrities, from last year's nominee Anne Hathaway to Tim Daly and Kerry Washington, through the melee at the Democratic Convention in 2008.
