"Transformers" beauty Megan Fox pays homage to Old Hollywood glamor with 40s style retro side-swept waves.

Get her look: After applying mousse to towel-dried hair, blow-dry using a round brush. Curl small sections with a 1-inch curling iron and pin them up with bobby pins for 10 minutes until cool. Remove the pins and brush hair to get soft, cascading waves.

Subtle waves with a piecey texture look effortlessly chic. Coupled with choppy eye-skimming bangs, this tousled 'do is the perfect complement to Mischa Barton's girlish looks.

Get her look: Apply volumizer to the roots of wet hair and create a center part. Use Velcro rollers to curl hair, rolling up to your chin, and let dry. Gently remove curlers and mist the waves with hairspray. To style the bangs, spritz hairspray onto a comb and comb through.

Tumbling wavy locks like Fergie's that are worn just a tad messy look incredibly sexy.

Get her look: Add a texturizing spray to wet hair and blow-dry with a two-inch round brush. When dry, create a center part and wrap sections of hair vertically around a 1 ½-inch curling iron. After curling entire head, gently pick up sections and shake them out for a slightly tousled finish.
