Peter Andre has postponed the rest of his UK tour to be by his cancer-stricken brother's bedside, who has been given two days to live.
The 39-year-old singer heard the news while preparing for Friday night's gig in Cardiff.
The 'Mysterious Girl' hitmaker agreed to perform but all other dates between now and Christmas - including Saturday's Liverpool show - will be rearranged for the New Year, the Sun reported.
His brother Andrew had been responding well to treatment but his health worsened last month.
Andre's family are flying from Australia to be at his side in a London hospital.
"Peter loves his fans and is loathe to let them down but he is sure they will understand," a source said.
Peter's spokesman said: "He is in bits. This has come as a big shock."
"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.
"Fortunately it has been possible to reschedule the five remaining 2012 dates on the Up Close and Personal Tour to take place following his pre-existing shows in January 2013," the spokesman added. (ANI)
