Amy Winehouse has sparked concern over her mental state after the soul crooner was spotted roaming the streets of London in her bra early Sunday.

The Daily Mail reports:

Barefoot, and clad only in her bra and jeans, the troubled singer emerged from a friend’s house in Bow at 5.45am on Sunday looking distressed and agitated.

Onlookers said she appeared disorientated as she wandered around on the pavement for several minutes in the freezing cold before disappearing back inside.
