It must have been difficult for Katy Perry to decide who to cheer for during England's World Cup match against the USA yesterday.
As an American, but with a British fiancé in the form of comedian Russell Brand, her loyalties were clearly divided.
So instead of choosing to back one side or the other, Katy Perry showed her support for both teams when she stepped out wearing a rubber dress which had one half made from a Union Jack flag and the other from an American Flag.
