Stars without make-up
Stars without make-up: Alexa Chung
Even stars can't look perfect all the time.
These celebrity faces have all braved venturing out without makeup and been photographed in their natural state.
It's clear why some are famed for their good looks - Alexa Chung, Kate Winslet and Beyonce Knowles look just as gorgeous without any slap on.
Others appear even younger when they're not glammed up. Nicole Richie is fresh-faced after being stripped of her beauty products while without makeup Kirsten Dunst could be mistaken for a teenager.
Fearne Cotton, Kylie Minogue and Rachel Stevens all have flawless complexions and Keira Knightley is radiant.
Confident celebrities including Claudia Winkleman, Leighton Meester, Jo Whiley, Anastacia, Edith Bowman and Alicia Silverstone just don't seem bothered about being without makeup.
These beautiful ladies grin happily when snapped by the camera, despite having been caught in a rather more casual fashion than usual. Megan Fox even chooses to share a no makeup shot on Instagram.
Other stars show their bare skin for charity.
Brave Caroline Flack, Lulu, Sian Williams, Julia Bradbury, Abbey Clancy, Jodie Kidd, Louise Redknapp and Heidi Klum have ditched their foundation for the Children In Need BearFaced Campaign.
However, some don't appear so pleased about being pictured without their warpaint.
Lauren Goodger and Eva Longoria try to shield their no makeup faces with dark sunglasses, while pretty Mila Kunis needlessly hides her eyes underneath a baseball cap.
Mel B puts a red scarf in front of her scrubbed cheeks and an unimpressed-looking Vanessa Paradis screws her face up at being noticed with no makeup.
Unfortunately for Sheryl Crow and Holly Willoughby, it appears as though they've been caught just after stepping out of the shower.
Neither managed to dry their hair before heading outside. Luckily, their good looks help them get away with being a little on the dishevelled side.
