Most celebs wouldn’t be caught dead without makeup, but in some cases, they might have been better off! Rest assured ladies — even the most glamorous stars fall victim to makeup mistakes. From Drew Barrymore to Jennifer Lopez to Jessica Simpson, we’ll take a look at Hollywood’s biggest beauty blunders.

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.
