SoFLa Local: Lady Gaga Draws Young Hollywood to New Year's Gig

At Lady Gaga's New Year's Eve poolside performance at Miami Beach's Fontainebleau Hotel, the outlandish performer wasn't the only star on display: A gathering of single, Young Hollywood types were in attendance – with some as mesmerized with each other as they were with the singer.

According to an eyewitness, Hayden Panettiere, 20, "was dancing, front and center" with Kevin Connolly, 35. The two were "chatting in the VIP lounge at the pool during the concert, and at the afterparty at LIV [nightclub at the Fontainebleau], they were sitting together. They were chatting all night, and they were very close to each other all evening."

The pair even shared a classic date food: Domino's New Pizza slices together poolside, says the eyewitness.

Lady Gaga performed four songs, including "Bad Romance" from her current album, Fame Monster. Others in the audience included Chace Crawford ("He was singing to Gaga's songs," says a source), blogger Perez Hilton (sporting a head-to-toe floral ensemble), former Desperate Housewives actor Shawn Pyfrom, The Hills' Frankie Delgado, former boybander J.C. Chasez and actress Stacy Keibler.

The Afterparty

After her set, Gaga "and over 20 of her dancers and production crew ate Domino's New Pizza. She spent over three hours backstage after the concert with her dancers. She thanked everyone individually for everything they had done in 2009," a source stated.

The performer then headed to her 3,000-sq.-ft. penthouse where, a partygoer says, "the afterparty raged on until the wee hours of the morning."

As for the setting, the $35 million penthouse rents for $15,000 a night. "Lady Gaga has four bedrooms, a kitchen, whirlpool and amazing balcony overlooking the ocean," a source said.

At the afterparty at LIV nightclub, in addition to Panettiere and Connolly, celebrating stars also included rappers Chris Brown, Bow Wow and Akon, who showed up via Diddy's private dinner party on the tony residential community of Star Island. A source says, "Chris was in great spirits, but once he was inside, he stuck to drinking bottled water. He pretty much kept to himself, hanging out with Akon."

Lady Gaga: New Year's Eve's Hottest Ticket?

Lady Gaga is playing the Fontainebleau in Miami Beach on New Year's Eve, and has sold over $1 million in tickets:

"The 'Poker Face' singer is said to be getting about 300,000 dollars for the show. Based on sales through website http://www.newyearseve.com/, tickets for the singer's performance to ring in 2010 are almost non-existent, with only a few 25,000-dollar tables left and some general admission seats at 425 dollars."

Guy Trebay pays tribute to Gaga in an end-of-the-year column:

"Although Andy Warhol died just a year after Stefani Germanotta came into the world, and decades before Lady Gaga was willed into being, he was correct as usual in forecasting a time when there would be 'new categories of people' being 'put up there' as stars. Those people, he wrote in 'The Philosophy of Andy Warhol (From A to B and Back Again),' would be made up of parts. And their fans, freed from the obligation to idolize a 'whole person,' could choose which dimension of a star they wanted to love. Lady Gaga is rigged for that stardom: her persona is an amalgam of surfaces, faceted though not truly 3-D, addictive in the way video games are."
