The brave actor reunited with his former Home And Away co stars Lynne McGranger and Ada Nicodemou, on Friday as they attended Claire McLennan and Nick Savage's wedding.
The star looked fit and healthy as he posed alongside his pals for the picture, which was uploaded to Lynne’s Instagram account.
In February, Lynne gave Home And Away fans an update on Johnny's condition during an appearance on The Morning Show.
'Johnny is doing really well ... he is in great form, he is still having ongoing treatment but it's working,’ she said.
'They don't continue treatment like that if it is not working but it's working and he is in such great form.
'He did have a couple of days where he is a little off colour and a little tired but then he is old Johnny again.
'He looks fabulous, he looks really strong and he is living a clean life which is words I never thought I would say in the same sentence as Johnny Ruffo but there you go.'
Last August, Johnny revealed that he was battling brain cancer, and in December he underwent surgery to have a tumour removed.
