Sometimes, even the most stunning of celebrities get their makeup wrong. Take a look through some of their worst beauty moments alongside some of their best.
Beautiful women, bad makeup
We love statement lips, but this bright red shade makes Nicola look pale and washed out. Neutral tones of lip gloss and blusher are far more complimentry to her complexion and hair colour.
Lawson usually goes for the natural look at public appearances (left). But at a book signing this week (right) she showed up with an extreme vampire-style look - blood-red lips, pale skin, and dark hair. Perhaps the star is a fan of Twilight or True Blood?
The singer was photographed leaving Nobu in New York with rings of iridescent eyeshadow, and the rest of her face was seemingly bare. Quite a look, Lily!
Yikes! Does Ms. Miller own a mirror? From the looks of her orange lips and thickly penciled brows, the answer seems to be no. All Sienna needs to look camera-ready is some mascara, a touch of blush and pretty pink lips.
No one likes letting go of sun-kissed summer skin, but heaping on bronzer is never the answer. The Welsh beauty is at her best when she plays up her Snow White complexion.
This is the woman who swept the president of France off his feet? Though Carla Bruni's appeal is obvious with her soft, understated makeup, she looks like a wood elf when she takes the scrub-faced look to extremes. Aren't world-famous models supposed to know how to put on makeup?
Posh's dark eye-shadow and eye-pencil emphasise her chocolate brown eyes and her neutral lip colour compliments her skin tone perfectly. Her attempt to look ultra-sophisticated at this year's CFDA Awards however, backfired big time. Her severe up-do, too-red lips, shimmery shadow and blush overload makes her look like she could be David's mother, not his mate.
Not long ago Amy's signature beehive, winged eyeliner and pale lips made her stand out in the music scene - in a modern, iconoclastic way. Today, the hard-partying songstress looks as though she's had one big night too many, and neither her body nor her foundation has survived intact.
Kelly's jet black hair, bright red lips and ghostly skin look a bit too Marilyn Manson inspired. It's good to see she's got a healthy glow back. Kelly's statement eyes and neutral lip gloss look gorgeous too.
Okay, we know you're a girly-girl. But, honey, you're only 25, which means that now's the time to play up your fresh-faced sweetness. The too-blue shadow, bold black liner and overly-oranged cheeks age you. Even you look surprised.
