Married At First Sight star John Aiken, 55, broke down in tears on Friday night as he talked about his co-star Mel Schilling's terminal cancer diagnosis
Fighting back his tears, John went on to reminisce over the 'precious moments' he has spent with Mel behind the scenes of MAFS since she joined the show in 2016.
'I've spent a lot of time over the last 24 hours just going through photos and listening to music because she's a very big fan of 80s music,' he said.
'A lot of people don't realise that before we go on set we're often singing and dancing in the hair and make-up room before we go on and call out bad behaviour on the set with these couples.'
John also commended Mel for being an 'amazing mum' to her daughter Maddie, 10, whom she conceived through IVF with her husband Gareth Brisbane.
'She's a real force to be reckoned with. A force of nature. She would fly over from the UK, she'd do our show,' he said.
'She'd have to fly back several times, but always at the forefront of her mind was her daughter Maddie and her husband Gareth.
'They were a driving force for her and I would often see her as I was getting made up; she was out the back FaceTiming Maddie, taking photos, getting fashion checks from her.'
John went on to say he hopes he gets a chance to fly back to the UK and 'say goodbye' to Mel, as his co-star recently said she doesn't know how much longer she has left to live.
