Fresh doubts have emerged over Robbie Williams's planned Australian tour, with reports that he cancelled the Asian leg of his tour due to depression. The Daily Mirror in the UK says Williams is "being treated by Dr Mark Collins, a top expert at the Priory clinic in South West London". Don't panic quite yet if you've got tickets to one of his two Suncorp Stadium gigs, though. At this stage at least, Williams's Australian tour is officially going ahead.
