Amy Winehouse revealed a bandage on her arm during a shopping spree in London.

The DailyMail reports that she was out last night with her father Mitch and some friends when she removed off her black jacket in the clothes store in front of the shopkeeper to try on a hooded jumper. During the quick strip, the Rehab star showed off a gauze strapped across the veins of her right arm.

While the cause of the injury is unclear, one thing is for certain - her red bra is definitely a favourite.

It made its first appearance last month when Amy was spotted wandering the streets of London's Bow in the middle of the night.

Earlier this month, as she returned from the Caribbean, it made another public appearance when she stripped at Heathrow airport to change her top.

Amy has been struggling to cope while her husband Blake Fielder-Civil is in prison awaiting trial for perverting the course of justice, a charge which he denies.

This shopping trip was her first public appearance since she attended Blake's hearing at Snaresbrook Crown Court on Friday.
