"Peter is devastated. He was very, very close to his brother," a spokesperson for the singer and reality TV personality told The Mirror.
"This is the very first family member Peter has experienced losing. He just needs time to grieve."
A friend of the family added: "Everyone was with [Andrew] when he passed away. They all did everything they could for Andrew, and there wasn't one waking minute when he wasn't with somebody."
Peter Andre had moved Andrew and his family over to the UK earlier this year for specialised treatment at the Royal Marsden Hospital.
