If it's Oscar night, then Sienna Miller is finally out of sight

It was her off-screen performance that made Sienna Miller the hardest working actress in Hollywood this season.

She schmoozed endlessly at cocktail parties, lunches and awards shows to promote her film "Factory Girl," which gathered no awards, or even awards buzz, despite her best efforts and Harvey Weinstein's considerable pull.

In less than a month, Miller presented at the Palm Springs International Film Festival, hit the Screen Actors Guild Annual Tea the next day, was feted with a lunch at Mr. Chow, hit the "Bobby" Globe nomination party at Drago, unveiled Godiva's One Million Dollar Hearts on Fire diamond shopping spree at Century City, and hosted a chic Chanel dinner (with Lauren Hutton, Lindsay Lohan, Cameron Diaz and Dustin Hoffman) at Chateau Marmont for a new couture fragrance line.

She was also a presenter at the Globes but got less-than-stellar fashion reviews for her Heidi-Ho braided do and Marchesa dress designed for her by Georgina Chapman, Weinstein's squeeze.

Still, she gamely snapped photos of photographers at the Weinstein post party in Trader Vic's and made an appearance at the WB/InStyle bash. Lastly, she opened the Santa Barbara International Film Festival with, oh yeah, her film about Edie Sedgwick, Andy Warhol's doomed muse who was born — and died of an overdose — in Santa Barbara.

Asked about her non-stop awards season activities, Miller explained, "This is the first time I have really had to carry a film and I felt a responsibility to support it. Besides, Harvey can be very persuasive. But I'm looking forward to going home."

No offense, Sienna, but we're glad you're going home too.
