Kate Middleton - She has impeccable fashion sense, but the Pricess of Wales could have spent a little more time on her makeup.

Sofía Vergara - The actress veered a little outside her natural lip line here. Try a contour pencil to avoid this.

Kim Kardashian -

The socialite, who has her own brand of makeup products, went a little overboard on the highlighter.

Nicole Kidman - The actress has two shades across her face. Those with very pale skin need to be careful when using foundation and concealer.

Angelina Jolie - The actress usually adopts a simple look, but here the lights and illuminator leave her looking a little too bright.

Tilda Swinton - The lack of eye makeup gives the impression that her eyes are much smaller than they actually are. (Although that's also the unusual-looking actress's signature look!)

Jessica Alba - Special care should always be taken when applying concealer under the eyes. If the color is too pale, it will only highlight what it is supposed to conceal.

Kelly Osbourne - A major fail! This two-tone look is more than a little odd.

Miley Cyrus - The singer has uneven foundation.

Tyra Banks - The supermodel ended up with a mismatched neck and face.

Christina Aguilera -

A double dose of error: concealer and highlighter used in excess around the eyes have left an obvious ring.

Jennifer Lopez - Excessive tanning and concealer do not match, so the area around her eyes has become streaked.

Taylor Momsen -

Gothic overload. The singer used far too much black liner.

Kerry Washington - Here the actress has two issues: a bad choice of concealer, and the color of the lipstick, which is too close to her skin tone.

Tori Spelling - Again, a bit too much blush.

Nicki Minaj - The rapper is known for her extravagant makeup style, and this image is a perfect example of her over-the-top application.

Kristen Stewart - The actress looks washed out and could benefit from a little concealer and blush.

Cate Blanchett -

Use too much powder and your face can disappear.

Taylor Swift - Her white-blonde hair clashes with the singer's understated eye shadow.

© Getty Images

Courtney Love - The singer has overdone the blush. This is a common mistake in people with very pale skin.

© Getty Images

Lil' Kim - The rapper is known to go wild with the face paint and often disrespects the natural contours of her face.

© Getty Images

Katy Perry - The singer has a paler than usual face here.

© Getty Images

Rachel McAdams - The actress could improve her look with a corrective base.

© Getty Images

Lisa Kudrow - Looks like she's used the same tone of eye shade, blush, and lipstick.

© Getty Images

Salma Hayek - Overuse of the eye pencil gives the impression of smudging along the bottom lashes.

© Getty Images

Scarlett Johansson - Likewise, the uneven edges of her eyes suggests that the actress had an unsteady hand.

© Getty Images

Rita Ora - The singer was probably going for a fierce appearance, but the excess highlighter in her T-zone has given the impression of oily skin.

Nicole Scherzinger -

An oil-free foundation would have been a safer bet. The result here is a little shiny.
