Looking to beat the midweek slump with an exciting evening out, Ashlee Simpson and Bar Refaeli both hit up Hooray Henry’s nightclub in Hollywood last night (September 11)

The Israeli-born supermodel was gorgeous in a long black dress with tie-dyed hemline accents, while Ms. Simpson served as arm candy to her boyfriend Evan Ross.

Ashlee recently confessed that her love for clothing began years ago when she discovered the wonder of MC Hammer’s parachute trousers!

Simpson explained, “In kindergarten I loved hammer pants! Fashion really starts in those [younger] years, and I started with hammer pants."
