J. lo and other stars go hairdo halfsies

Crowning Glory: Jennifer Lopez blazes a bold trail with this trend, coupling beachy waves with a high, perky topknot.

Glossed Over: Modern Family star Ariel Winter pulls a wide swath of her glossy locks back from her forehead for a Marsha Brady-inspired retro look.

Wave Rider: Whitney Port puts a pretty spin on the half-up 'do, with wavy, twisted-and-pinned locks on top.

Drama Class: A deep side part adds contrast to Kristen Bell's scraped-back locks, which—full story—are gathered in a pretty braid in the back.

Bang-Up Job: Lea Michele's full fringe and pulled-back strands create a look that's sweetly innocent.

Up and Down: Fresh face Emily Meade (Young Adult) wears a red-carpet 'do that is refined but casual, sweeping the top of her hair back while draping her shiny blond strands over her shoulders.

Top Notch: Maria Menounos takes a cue from J.Lo with her own voluminous waves and playful half-up pony.

Twilight Time: A pretty pouf, loosely pulled back from her forehead, adds a touch of drama to Anna Kendrick's feminine waves.
