Grammy-winning singer Adele thanked fans for their birthday wishes in a special message on Twitter along with a photo of herself dressed up as another famous Brit—George Michael.

Adele is unrecognizable as the “Faith” singer, complete with ’80s-style slicked-back locks, facial hair, and aviator sunglasses. She called Michael her “hero,” and assured fans she had a “wonderful time” on her birthday.

No word yet on when the singer will be releasing her next album. Her most recent compilation, 21, was released in 2011.
