Why are these celebs taking selfies in bed?

There appears to be a new charity craze sweeping social media - #wakeupcall, in which the famous take pictures of themselves after they’ve just woken up.

UNICEF has begun the campaign to raise money to support their work with children in Syria. The task is simple: Just take a photo of yourself as soon as you've woken up, post to a social network with the hashtag #WakeUpCall, donate £5 (Rs 494) to UNICEF and nominate three friends to do the same.

And in the spirit of charity some celebs have taken the challenge. Here’s their #wakeupcall
