Peter Andre is currently in Dubai for work, but was reluctant to leave his brother.
Andrew, 54, is battling cancer and moved to Britain from Australia to be looked after by his sibling - but things didn't get off to a good start.
'He suddenly became very unwell and collapsed, which was really frightening for all of us,' says Pete, 38.
Fortunately Andrew, who was diagnosed with kidney cancer in February, is now out of hospital after being rushed to A&E.
'Andrew's doing much better now and is back at home,' says Pete, 'but we still don't know exactly what triggered his collapse.
'He begins his chemotherapy this week, so we'll all be supporting him as he goes through that.'
