Actress Christina Applegate is seen at the 35th People's Choice Awards sporting a classic shoulder-length bob with a center part. Part of the allure of this hairstyle is its understated elegance, which makes it appropriate for any occasion. Plus, thanks to its simplicity, styling is a cinch.

Get her look: Spritz styling spray on wet hair. Style by blow-drying hair with a large round brush, slightly rolling the ends under with the brush as you blow-dry.

"Bride Wars" star Anne Hathaway does a modern take on the '50s flipped 'do, complete with teased height and a satin hairband at the New York City premiere.

Get her look: Straighten hair using a flat iron. To create the flipped ends, blow-dry using a small round brush -- curl ends outward and set the style with a blast of cool air before releasing. Add height by teasing roots at the crown, then slip on a sleek hairband.

There's something sexy about messy just-got-out-of-bed hair. On "Twilight" star Kristen Stewart, her tousled textured style is uber hot in a laid-back way.

Get her look: To get a really textured finish like Kristen's, you need styling products that help define the layers. Apply mousse to wet hair and let dry. Rub wax or pomade between your hands, then grab random bits of hair and smooth product from mid-shaft to end. Pull strands in different directions to create the tousled look.

Denise Richards shows that big hair is sexy with her messy bouffant worn in an half-up half-down style at Prive Nightclub in Las Vegas.

Get her look: The trick to getting this much volume is lots of teasing -- the technique of combing hair ends towards the scalp. First divide hair from ear to ear over the top of your head, and clip the front section out of the way. Then tease hair behind that section (at the crown near your scalp) to create the bouffant. Unclip the front section, gently smooth it back over the teased area with a bristled brush. Secure with a hair clip in an half-up half-down 'do.

New mommy Ashlee Simpson sports feminine, piecey waves at the new year eve's celebration at Pure Nightclub in Las Vegas.

Get her look: After washing hair, apply volumizer to the roots. Curl hair in Velcro rollers, rolling up to chin level. Let dry or blow-dry on a low setting, then carefully remove curlers. With a little wax spread between palms, gently cup the waves and scrunch. To finish, run fingers through hair to separate it for a piecey look.
