The songstress, who sings the theme song for the 3D epic, looked stunning in a full-length bejewelled dress, which sparkled all the way down the blue carpet.
Meanwhile the films leading ladies Zoe Saldana, Michelle Rodriguez and Sigourney Weaver looked somewhat drab in comparison.
Other guests included Cuba Gooding Jr, Giovanni Ribisi, Jamie Lee Curtis, Danny DeVito and Audrina Patridge who won the award for the worst dressed star of the night.
