You've seen plenty of celebs strip down, but never like this before. Some of the biggest A-list beauties in the game are getting involved with the "Wake Up Call" challenge, an initiative created by UNICEF. The organisation is raising awareness and money for children in Syria. Women like Cindy Crawford, Naomi Campbell, and Cat Deeley are posting makeup-free selfies on Instagram and Twitter. Then, they nominate other stars to do the same, similar to the ALS Ice Bucket Challenge.
You don't have to be a celebrity to join in. Just tag your early-morning selfie with #wakeupcall and visit UNICEF's site to make a donation to the cause. It's bringing a whole new (charitable) meaning to #wokeuplikethis! Get plenty of pose inspiration from these gorgeous, fresh-faced women.
