K-pop group Big Bang’s member T.O.P uploaded a selfie taken while sipping a glass of wine, captioning it “Good Morning,” on Monday afternoon.

His mad-scientist hairdo drew many comments from fans.

Big Bang delivered a comeback concert on Saturday and Sunday, after a three-year hiatus since its last EP release in 2012. After Sunday’s concert, T.O.P updated his Instagram with a group photo, saying “Weren’t we great tonight?”
