IRISH celebrities are joining in the new social media craze that aims to raise money for victims of the ongoing war in Syria.
Hollywood superstar Liam Neeson (inset) is among those to have posted a just-woken-up picture to Twitter to help raise funds for Unicef.
GAA stars Dermot Early and Joe Canning have also posted their pictures as part of the trend, which is marked #WakeUpCall.
They have joined a host of international names including the BBC's Jeremy Clarkson, who shared a bed with chef Heston Blumenthal, and reality TV star Paris Hilton.
The craze follows similar pursuits such as #Nomakeupselfie which raised millions of pounds for Cancer Research.
More recently the ice bucket challenge raised money for research into motor neurone disease.
In both cases, members of the public were given the opportunity to see the rich and famous with their guards down.
As with the previous challenges, participants are urged to nominate friends to take a picture of themselves after just waking up.
The celebrity craze comes as Kurdish fighters continue to hold out against an IS onslaught in the Syrian town of Kobane, on the border with Turkey.
