Birthday Party Ideas for 14yr. old girl?

I am 13 turning 14. I love Black, Sliver, and Pink. I love dance, theatre, singing, swimming, scavenger hunts, art, music, making stupid videos, and sewing. I am super popular, so this has to be a good party. I want a sleepover.... just need a theme. It will only be me and 3 other girls or me and 4 other girls. Please...... NO STUPID OR IN-MATURE IDEAS!!!!
