The socialite was front and center in the deejay area at the party – which also drew out guests such as Emma Roberts, Gerard Butler and Usher – where she shouted at the crowd and twirled around in her dress.
"At one point, she started swinging her head in circles," says an onlooker. "Her hair was flying everywhere. She was definitely having a good time."
Earlier in the day, the socialite and her deejay boyfriend Afrojack were attached at the hip in a private cabana at a Chevy Volt party.
