The A-listers were out in full force at the annual amfAR Cinema Against AIDS Gala in Cannes, France Thursday night. And while the star-studded event was also a benefit for charity, celebs weren't afraid to cut loose and let their hair down!

A single and Marchesa-clad Heidi Klum took the stage to auction off a rose gold Cartier watch, which went for a whopping $62,665 bid. "Heidi even threw in a massage for good measure!" a witness tells Us Weekly. Later the mom of four (who filed for divorce from her husband of seven years, Seal, earlier this year) was seen dancing with a female friend to The Beatles' "Twist and Shout."

Kim Kardashian, who has been popping around Cannes with her boyfriend Kanye West, hit the party (in Elie Saab) without her beau but spotted a woman in an outfit she had worn earlier in the week.

"I just wore that here, it looks great on you!" the E! star was overheard telling the fashionable passerby, who thanked her for the compliment.

Speaking of beaus, Kirsten Dunst was joined by her boyfriend, Garrett Hedlund, who arrived at the event a bit late. "Garrett and Kirsten were pretty kissy during the dinner," an onlooker tells Us. "At one point he curled her hair back and whispered something into her ear and she beamed. She hardly touched her food."

One of the biggest bidders of the evening was Milla Jovovich, who won a L'Oreal Paris custom-made lipstick from the brand's Paris headquarters, complete with a Chopard diamond encrusted lipstick case. She also bid $12,518 to support an HIV-positive baby in Cambodia for one year.

But even with the abundance of Tinseltown beauties, it was inevitable that one celeb would fall mercy to a misstep: The Vampire Diaries' Nina Dobrev suffered an awkward moment when the announcer mispronounced her name.

Once she took the stage, Dobrev said on the mic, "No, it's Dobrev, but I guess you got it close enough so thanks for that." A witness tells Us, "[Her correction] definitely turned off people who didn't know who she was."
