Cate Blanchett rocks the Cannes opening night carpet!

Cate Blanchett gave birth to her third son on April 13 in Sydney, Australia.

One month later, she's already back to being svelte and glamorous on the red carpet for the 2008 Cannes Film Festival's opening night film, "Blindness," wearing an ethereal pale peach chiffon pleated one-shouldered Armani Prive gown.

Okay, how does she do it? And where can we buy it?

The  actress will be forgiven for skipping tonight's hot ticket "Blindness" post-bash at the Carlton Beach, where the film's star, Julianne Moore. will be holding court.

Hopefull by party time, the red-haired actress will have managed to shake loose the crazed crows seen roosting on her Christian LaCroix couture gown. Pesky critters, French Riviera crows. And fearless!

But Cate will certainly be called back on the carpet for the world premiere of "Indiana Jones and the Kingdom of the Crystal Skull," on May 18, with Harrison Ford and Steven Spielberg.

The mad cap couture show has only just begun. Top international design houses and accessory companies such as Roberto Cavalli, Giorgio Armani, Swarovski, Chopard, Bottega Veneta, Balenciaga, Jimmy Choo, Dolce & Gabbana, and Fendi are already installed in various suites in luxury hotels along the Croisette. All the suites are chock full of glam gear to keep all the actresses suitably attired for the tres formal events going on for two weeks.

Hot steamy party poop scoop: Fendi is hosting the after-party for the ever-glittering amFar gala on May 23. And  Margherita Missoni will headline the Quintessentially (an international private members' club) party aboard the mega-yacht Pegasus on May 16.

And I hear through the grapevine that Victoria Hart, the singing waitress plucked from obscurity by George Clooney to sing at his Darfur Now fundraiser last year, will sing at the Quintesstially fete while limited edition bracelets by Greek jeweller Ileana Makri are sold to raise funds for OrphanAid Africa.

These wealthy Cannes-doers sure know how to mix charity with party pleasure.
