Natalie Portman looks super sexy with this tousled side do!

1. To get Natalie's look, wash your hair with a volumising shampoo and conditioner and apply a small amount of mousse to towel-dried hair.

2. Blowdry the hair with a large round brush and try and get as much height at the roots as possible. Once dry, create a side parting and pull the hair round into a side ponytail. Take sections of the ponytail and twist before pinning into a bun. Do this until the whole of the ponytail has been pinned up.

3. Allow a few strands to fall loose and finish the look with a strong hold hairspray to ensure your do lasts all night!
