The vamp eyes – a signature Mary-Kate look

Here we find them at their best — and hair-raising worst!

Here, Katherine Heigl shows us how to do waves the right way with her old Hollywood glam look. But with too much product her locks look dingy — not to mention straight out of “There’s Something About Mary!”

Please tell us this mullet-inspired chop job is for a movie role! Hopefully Jada Pinkett Smith‘s hair will grow out soon to our preferred look — shiny and sleek.

Only Bo Derek could be a perfect “10″ in cornrows. We’re glad Christina Aguilera has traded her Dirrty ‘do for Marilyn Monroe-inspired platinum blonde waves.

No wonder Victoria Beckham started a blunt bob trend in Hollywood — it suits her perfectly. In her stodgy up-do, however, she looks like she’s taking her reputation as an ice queen a little too seriously.

How did L.A.’s biggest party girl end up with a soccer mom haircut? Luckily, Paris Hilton soon grew her ‘do into a perfectly flirty asymmetrical bob.

Katie Holmes proves that all the money in the world can’t buy perfect hair. Mrs. Cruise’s tousled tresses look childish next to her signature sharp bob and bangs.

She’s known for her eccentric style, but Mary Kate Olsen‘s Marc Jacobs’ headband makes her look more aerobics instructor than fashion icon. MK should stick to long, messy blonde tresses for black tie events instead.

Hey, Fergie — Bret Michaels wants his look back! The Glamorous star looks the part when she wears her honey hair wavy and free.

Scarlett Johansson‘s super-poufy beehive doesn’t create much buzz, but her blonde hair looks gorgeous in cascading waves.

We didn’t realize that Alicia Keys was such a fan of the Coneheads! The No One singer looks much better in her natural curls.

Ever since Evan Rachel Wood began dating rocker Marilyn Manson, her style has taken on his goth tastes. We, however, prefer the original.

Beyonce

When Beyonce looks good, she looks fabulous. When Beyonce looks bad,… let’s just say, based on the photo at right — her own family wouldn’t even be able to identify the body. The pale foundation is bad enough, but the blood red lipstick just amplifies the creepy.

Drew Barrymore

If Drew were on her way to a Halloween party, we might understand this look. Unfortunately, she caked her face with white powder for the London premiere of her blockbuster Charlie’s Angels. Scary!

Amy Winehouse

Not long ago Amy’s signature beehive, winged eyeliner and pale lips made her stand out in the music scene — in a good way. Today, the hard-partying songstress looks as though she’s had one big night too many, and her foundation hasn’t stood up.

Christina Aguilera

Ms. Aguilera loves to emulate Marilyn Monroe’s blonde bombshell style, but shiny red lips, heavy eyeliner and way too shimmery shadow hide the Beautiful girl underneath.

Fergie

Same pose, different face! She’s got the eye makeup and blush, but Fergie must have forgotten her foundation at home. Smooth even skin paired with bright defined lips help Fergie look truly Gorgeous.

Jennifer Lopez

J. Lo positively glows in the fresh faced look on the left, but an overload of shimmery charcoal eyeshadow and too-nude matte peach lips weighs her down.

Jessica Simpson

It’s Jess the Joker! Simpson admitted to over-plumping her pout with Restylane, and this bright red lipstick sure didn’t help.

Teri Hatcher

Teri — don’t look so surprised. That charcoal shadow didn’t work for J. Lo, either!

Liv Tyler

Liv’s pale skin looks pasty next to her black-rimmed eyes and bright pink mouth. She looks healthier — and younger — when she sticks to clean, minimal makeup.

Avril Lavigne

Not wanting to be overlooked at her CD release party, Avril pulled out all the stops, including red lashes, exaggerated liquid eyeliner and plenty of glitter.

Mandy Moore

All the color in Mandy’s face seem to be concentrated in her blood red bow-tie lips. We prefer them fuller, in sweet pale pink.

Brooke Hogan

Apparently, Brooke doesn’t know best! Did the reality star put her makeup on in the dark? She seems to be a little heavy handed in her application.

Kirsten Dunst

Proof that the wrong shade of lipstick can make or break a look, Kirsten’s red lips are too orange based for her complexion, and highlight a less than stellar smile.

Mary-Kate Olsen

Mary Kate’s invisible lips are a wash out! She looks positively angelic when her baby blues are paired with a pretty pink pout, but with nude lipstick and brown shadow rimmed eyes, MK looks sickly.
