EVERYBODY SMILE: High-profile guests arrived at the Regent Beverly Wilshire hotel Thursday night for Operation Smile's fifth annual LA Gala. Roma Downey co-hosted the event with ``Access Hollywood's'' Billy Bush, ``Survivor'' mogul Mark Burnett, Vanessa and Donald Trump Jr., Norm Nixon, Elton Brand and Jeffrey Katzenberg.

Doris Roberts, who was there with friends, said, ``It's just a wonderful thing that so many people give their time and money to help such a great cause.

``When you see even one child's smile helped by surgery, you realize how important this is.''

After a cocktail party where guests mingled and browsed over the auction items -- which included donated jewelry and artwork by Dali, Picasso, Chagall and Miro -- the evening literally kicked off with a rousing performance by the Debbie Allen Dance Company, followed by a heartfelt video presentation by Downey.

Bush told a lame joke that elicited more groans than smiles from the audience, but he made his point -- that a smile is all-important to a child with a facial deformity.

This year, the event honored the Trump family for their humanitarian efforts worldwide, as well as Nixon and Brand. When Trump Jr. and wife Vanessa took to the stage, they soon had guests donating an additional $750 each to fund a surgery, while sponsor Lladro donated a check for $150,000 to the cause.

No wonder everyone was smiling as Christopher Cross and his band wrapped up the night.

LENS OF A WOMAN: ``This event used to honor real working women in film,'' a production designer was overheard grumbling. ``Now you only get invited if you know a celebrity honoree.''

It certainly was an elite selection of A-list stars and up-and-comers who attended the 13th annual Premiere Women in Hollywood celebration on Wednesday night. The elegant yet relaxed dinner was held in the grand ballroom of the Beverly Hills Hotel.

This year, Premiere Magazine honored five leading lights of Hollywood, who, coincidentally, all have major movies or TV dramas launching within the next few months. Amy Pascal, newly promoted co-chairwoman of Sony Pictures, was holding court -- and rightly so, as it was she who had the courage to back the lavish biopic ``Marie Antoinette,'' directed by Sofia Coppola, one of the night's honorees. Sofia's award was presented by Anjelica Huston, who praised Coppola for her endurance, persistence and talent, highlighting their commonality that included ``both experiencing vulnerable moments when we had not yet grown into our noses.''

Acting legends Gywneth Paltrow and Warren Beatty talked about the reason they were there: Annette Bening's Icon Award. They mingled with leggy ing(hrt)nues such as Leelee Sobieski and Amber Tamblyn. Rachel Griffiths presented to her ``Brothers & Sisters'' co-star, the diminutive Sally Field. Judi Dench was on hand to present an award to her ``Notes on a Scandal'' co-star Cate Blanchett. Edward Norton presented the Chanel Spotlight award for emerging talent to his ``Down in the Valley'' co-star Evan Rachel Wood. He confessed that he used to listen to recordings of Dench's famous Shakespeare performances.

Apparently Blanchett didn't get the ``serious women in film wear black'' memo -- and dazzled with an unusual pink-gold gown with a stiff, ruffled collar and gathered sleeves. Griffiths and Christina Applegate had the misfortune to turn up in the same black floral print dress, but both took the fashion faux pas in stride.

LADIES LUNCH FOR A CAUSE: It's a little early to begin Breast Cancer Awareness month (which is, technically, October), but nonetheless, Estee Lauder Cosmetics and Saks Fifth Avenue jumped the gun for the good cause on Wednesday afternoon with a very chic ladies' luncheon at the Greystone Estate in Beverly Hills.

Gwyneth Paltrow was the woman of the hour. She and Aerin Lauder (Estee's granddaughter and the company's head honcho) had earlier launched ``pleasures by Gwyneth Paltrow,'' a limited edition of pampering items including perfume, bath salts and body spray, at Saks, and pledged 100 percent of the day's profits to benefit the Breast Cancer Research Foundation. Lauder also will sell two lipsticks and two lip glosses in October, with proceeds going to the foundation launched by Evelyn Lauder in 1993.

Pretty faces and a few scary-skinny figures dotted the vast courtyard of the mansion on Doheny. Gorgeous Bridgette Wilson-Sampras and supermodel Carolyn Murphy looked fit and healthy while nibbling on tiny appetizers, but the waiflike Nicole Richie teetered on stick-like legs and declined even the smallest bite.

After the cocktail hour (during which most of the figure-conscious crowd sipped water) the bevy of beauties (among them Gabrielle Reece, Laura Dern, Wendy Braun, Monet Mazur and Garcelle Beauvais-Nilon) joined honoree Paltrow and special guest, breast cancer survivor Sheryl Crow, on a terrace overlooking the city for an elegant light meal of pea soup, lobster salad and berry tart.

Paltrow, whose voluptuous, cream-satin-clad figure reminded everyone that she recently had her second baby, Moses, reported proudly that ``I love being associated with Estee Lauder and am happy to say that the foundation has already raised more than $140 million to fund breast cancer research.'' She also called Crow ``totally inspiring'' for her personal and public fight against the disease.

Crow, looking tan and healthy, said that, for her, ``Cancer was a bit of a show stopper, a sort of life chiropractic adjustment,'' and that for now, she has beaten the disease. ``But I know firsthand that research is the only way we are going to find a cure, and hopefully that will happen soon.''
