(Cover) - EN Star Style - Natalie Portmans hairstylist has revealed how to create her stunning locks.

The 29-year-old actress always looks stunning on the red carpet, and her trusty hairstylist John D has explained how he achieves her bohemian-style flowing tresses.

At this weeks premiere for her new movie No Strings Attached Natalie sported a bouncy look, which oozed retro Hollywood glamour.

"Natalie's look was inspired by the 70s vibe of her long Vena Cava halter gown," her hairstylist John D told UsMagazine.com.

"A strong centre part with a bit of volume at the crown added to the glamour."

According to John, Natalies gorgeous style can be created using plenty of volumising cream before blow-drying with a large round brush. Sections of hair should then be wrapped around a curling iron, before messing up the locks a little and setting with hairspray.

In No Strings Attached Natalie portrays Emma, a girl who embarks on a frivolous relationship with a hunky man and insists things will remain strictly physical. Hollywood heartthrob Ashton Kutcher plays her love interest Adam. (C) Cover Media
