Th ere was megawatt star power at the Golden Globes on Sunday night, but it was of little help when the lights went out at the InStyle party at around 10 p.m. The already-packed lobby of the Beverly Wilshire Hotel, site of the televised awards show, became a logjam as stars scurried to find another place to party hearty.

The blackout was a boon to curious stargazers, who had a better opportunity to snag autographs and snap photos with the now well-fed and -watered stars.

A few folks headed upstairs to the Paramount party in the Stardust room, where the cast of the winning picture for drama, "The Hours" -- Globe-winning best actress Nicole Kidman, Meryl Streep (who won a best supporting Globe for "Adaptation") and the shut-out but not shut down Julianne Moore -- made a stylish threesome. Kidman was aglow, but Streep was aghast.

"I was shocked," admitted Streep, wearing a Giorgio Armani sequined jacket. "The thing about actors is that we are all deeply insecure and that's what makes you able to do the work, but it also makes you scared all the time."

The festive HBO party, held downstairs at Griff's restaurant, featured the definitely NOT scared cast of "The Sopranos" including Tony himself, James Gandolfini, and Edie Falco, who won a Globe for her role as Carmella, Tony's long-suffering wife.

Also on hand were other HBO Globe winners Uma Thurman ("Hysterical Blindness"), Donald Sutherland ("Path to War") and Larry David ("Curb Your Enthusiasm"). But all the photogs surrounded Tom Hanks, who was seated at the "My Big Fat Greek Wedding" table with his wife, Rita Wilson, who produced the film; the film's star/writer, Nia Vardalos; and her husband Ian Gomez.

"Sex and the City" sirens were the other big draw: Kim Cattrall, in a sexy red Valentino gown; Sarah Jessica Parker, in a va-va-voom black bustier with hubby Matthew Broderick; and Cynthia Nixon, in a demure yellow chiffon pastel party dress.

A sudden severe traffic jam in front of the "City" gals' booths occurred when eternal Playboy Hugh Hefner and his ever-expanding bevy of buxom blondes (we counted six plus one stray brunette) filed by to congratulate Cattrall on her award.

"What is this, January through September?" asked one frustrated party boy, trying to squeeze by the cookie-cutter cuties.

SEND THE BILL TO HARVEY The festive night was still growing strong when those pesky fire marshals clamped down on the Miramax bash at Trader Vic's, the place for everyone who wanted to see or be seen.

Michael Caine, with wife Shakira, and Cate Blanchett, in an embroidered Valentino couture gown and an Elaine Schwartz peacock diamond necklace, left early to have a quiet dinner, but Helen Mirren braved the crowd waiting to be let in. Even "Confessions of a Dangerous Mind" star Sam Rockwell had to plead with a security guard to be let past the ropes to the party, which was held in a tent outside near Trader Vic's.

But no wonder everyone wanted in. That's where new faces Maggie Gyllenhaal ("Secretary") and Kieran Culkin ("Igby Goes Down") were lurking, along with "Chicago" Globe winner Richard Gere and his wife, Carey Lowell. Gere's co-star Renee Zellweger, also a Globe recipient, was trading hugs and congrats with fellow winner Kidman, her co-star in the upcoming "Cold Mountain." Zellweger had been up for Kidman's role in last year's "Moulin Rouge."

"I think at one point all of us are up for the same role. But no one should have been on that swing but Nic," said Zellweger, who also sung the praises of "Chicago" director Rob Marshall. "He's not just a guy who directed a great musical," Zellweger raved. "He's a great director. I have never seen a guy multitask like he does. He had every reason to lose it several times, but he never did. Whenever the pressure hit, he would just giggle."

Also smiling at the Miramax party was the man of the hour, best director Globe winner Martin Scorsese, there with his "Gangs of New York" crew: Daniel Day-Lewis, John C. Reilly, Bono (he did the film's theme song), Cameron Diaz (with scruffy boyfriend Jared Leto) and a suited-up but smiling Leonardo DiCaprio, who hit the sushi bar twice. The solo star was surprisingly approachable, even to female fans who nervously sidled up and asked him to pose for photos in the packed party.

Even though the epic film didn't win any other awards, the "Gangs" gang was thrilled that Scorsese was honored. Leo even claimed it was "high time" for the director who's never won a Globe or an Oscar for his famed films.

"It feels fantastic," said Scorsese of his first Globe. And he's glad he won for this film and not before. "I think I had to go through making all those other films before I could properly do this one. I needed to find the personal story within the history."

"Chicago" hoofer Catherine Zeta-Jones didn't let a personal thing like pregnancy keep her from enjoying the party, so she stayed late chatting with male admirers while husband Michael Douglas, looking very thin and blond, circled the enormous bar a few times. The diminutive Salma Hayek ("Frida") got a crick in her neck from trying to talk to the eerily tall Jeff Goldblum, who was flirting with every female he made eye contact with. The Miramax party still had a line to get in when "Pianist" star Adrien Brody bailed. But he made time to pose for yet more photos with pleading teenage fans.

Day-Lewis, who had been a front runner for a Globe but lost to "About Schmidt" star Jack Nicholson (Jacko was partying at the New Line bash at Koi on La Cienega), didn't break his stride for such niceties. He was on his way to the men's room inside Trader Vic's and then disappeared out a rear exit door into a waiting limo. But Brody patiently went with his publicist to the front of the hotel, stopping by the gift-bag booth. When asked how many gift bags he wanted, he shrugged and said, "One?"

This guy's got our vote.
