Looks like those legal matters of Chris’ are preventing him from traveling overseas to the UK and Ireland to do that leg of his Fan Appreciation tour. He Tweeted that he had to cancel–without explanation–then deleted the Tweet. But now his PR group has given the official statement.
His PR group states:
Due to issues surrounding his work visa, the Ireland and United Kingdom leg of Chris Brown’s Fan Appreciation Tour has been postponed. Chris looks forward to performing for his fans abroad in the near future and thanks them for their continued support.
