Gossip Girl star Blake Lively fell foul of a rushed cover-up job at the 2009 Angel Ball in New York on Tuesday night.

As the gorgeous actress posed on the red carpet, the bright lights and camera flashes revealed some white patches on her decolletage that matched her pale foundation but not her tanned skin.

Concealer mishap aside, Blake looked impeccably stylish in a smart but edgy mini dress at the charity event.
