Some people wondered if Britney Spears would revert back to being crazy when she made the switch back to being a brunette from being a blonde. However, she’s looking perfectly sane to me.

Britney is all smiles as she and her son Jayden James Federline arrive at the airport in Copenhagen, Denmark. The pop princess has scheduled a concert at Parken Stadium and looks more than ready to take on the performance tonight.

Jayden is turning into one cute kid.
