The stars turned out to honor Jennifer Lopez, who was named Us Weekly's Style Icon of the Decade Thursday at Drai's Hollywood inside the W Hollywood.
The bash -- sponsored by Absolut Berri Acai, Motorola Cliq XT with MOTOBLUR, Piperlime and Sony Cyber-shot DSC-TX7 -- attracted the likes of Sheryl Crow, Kelly Osbourne, Twilight's Nikki Reed, Paris and Nicky Hilton, DWTS' Nicole Scherzinger and Karina Smirnoff and American Idol's Katharine McPhee, among others.
But the night belonged to Lopez, 41, who celebrated -- how else? -- by dancing!
At one point during the party, Lopez began playfully dirty dancing with husband Marc Anthony.
Clad in a nude Chantilly lace Georges Chakra Couture dress, The Back-up Plan star grinded up against Anthony, 42, while holding her Us Weekly Style Icon of the Decade award in one hand!
"The best part of the night was winning this award!" Lopez told Us.
Her pal Leah Remini told Us Lopez definitely deserved the honor.
"Jennifer is fearless when it comes to fashion, and she is always beautiful and always takes a risk," she told Us. "She doesn't care what people think."
And she gives perfect fashion advice as well. "I always say, 'Jen, what do you think?'" said Remini, who even had a mini dance-off with Lopez at Us' bash.
The night, she said, was "a time for celebration."
