On Thursday night, the Samsung Galaxy Note II release blasted off with an exciting party attended by top celebs like Christina Aguilera, Liam Hemsworth, Julianne Hough, and Vanessa Hudgens. The stars got to mix and mingle, while checking out all the new features of the device through fun interactive demonstrations.

Rosie Huntington-Whitely was seen jamming out at the DJ booth with DJ Zen Freeman. When they weren’t laying down the tracks, Kendrick Lamar and Toro Y Moi entertained audiences with performances of their new songs.  Do you Kendrick Lamar’s song “Drink”? Christina Aguilera and Vanessa Hudgens sure do, as they were seen singing and dancing together during his performance of the hit. Another highlight of the night included drinks courtesy of master mixologist Sam Ross, who chilled with Vanessa and Liam, while the latter talked about how excited he is for his upcoming marriage to Miley Cyrus.
