The singer and mum of one recently celebrated her 27th birthday, and shared this snap on her Twitter account of herself dressed as her idol.
'Thank you for the birthday wishes I had a wonderful time! I was my hero x #gottahavefaith' she wrote.
And it wasn't just us that were impressed by the likeness, as Mr Michael tweeted her back, saying:
'Happy Birthday @OfficialAdele !!! I'm so flattered, love The Singing Greek! xxx'
It's a LONG time since we've seen a costume this convincing - great job, and happy birthday Adele!
