By now, you may well be aware of the '#NoMakeupSelfie' trend, with women everywhere posting photos to social media without their makeup to encourage people to donate money to Cancer Research UK.
Michelle posted her selfie to her official Twitter page on Sunday morning, along with the phone number for making donations to the charity, encouraging others to do the same by saying: "It's so easy! Do your bit."
And the star has certainly proven just how easy raising awareness can be. The photo - which shows her slap-free while tucked up in bed - has been retweeted more than 7000 times since it was posted.
She may not be able to go makeup-free for long, though, as it was reported last week that after going on holiday to Dubai, she'd frustrated 'Corrie' bosses by coming home too tanned to film convincingly her last scenes as Tina McIntyre before she exits the soap later this year.
Even popstar and 'X Factor' judge Cheryl Cole is getting in on the act, sharing her "flawless" #nomakeupselfie with her 640,000 Instagram followers on Sunday morning.
