Australian singer Peter Andre has postponed the remainder of his U.K. tour after his cancer-stricken brother's health deteriorated.

The Mysterious Girl hitmaker arranged for his older sibling Andrew to fly to London for specialist treatment in March (12) following his kidney cancer diagnosis.

Andre has supported his brother throughout the ordeal, and has now axed the rest of his 2012 shows in Britain to be by his side after his health took a turn for the worse.

A statement from the pop star's representative reads, "It is with great regret that Peter Andre has postponed his remaining December 2012 tour dates... His brother Andrew’s health has taken a turn for the worse and Peter has made the decision to be with him and his family at this time."

The five dates remaining dates this year (12) on the Up Close & Personal Tour have been rescheduled for 2013.
