Pop superstar Madonna stunned security staff at an airport in Germany on Thursday night - by turning up wearing a bathrobe.

The Holiday hitmaker arrived at Schoenefeld airport after performing at the Olympic Stadium in Berlin as part of her Sticky + Sweet world tour.

But staff at the venue were shocked to see the star wander through security checks wearing nothing more than a fluffy white robe and black trainers.

The singer's gown had the cheeky slogan "Dancing Queen" printed on the back.
