Celebrity hair stylist Mara Roszak crafted Lily's slick strands and explains how she achieved the look to OK!:

• I started with Lily's dry hair, sprayed Elnett Heat Protect Styling Spray and rough dried it in to create a base for extra hold. Then I slightly damped the roots with water.

• Next I parted the hair deep to the side and applied gel with a comb to the damp roots, creating a very loose, smooth "S" wave onto her forehead, then clipped it in place to dry.

• I waved and set the rest of the hair with a 1 1/4" barrel iron, the sprayed L'Oreal Elnett Strong Hold Hairspray all over the head.

• Once the hair was all dry, I unclipped the hair and gently brushed out the bottom for a soft, waved look and sprayed with hairspray again.

• With long, black bobby pins I created a slightly staggered look around the head, allowing the style to stay flat to the head, and added a modern accessory with exposed bobby pins.
