Max George has revealed he will undergo his emergency heart surgery imminently in his latest health update from his hospital bed on Saturday night.

The Wanted star, 36, who has been in hospital for a week suffering from a 2:1 atrioventricular block and is awaiting a pacemaker, admitted he ‘feels like s**t’.

An atrioventricular block is a disorder that occurs when electrical impulses are delayed or blocked from reaching the ventricles.

Max previously revealed he was set to undergo surgery sooner than expected because his heart rate has ‘failed to pick up’

Now taking to his Instagram Stories, the singer appeared exhausted as he spoke with his followers and told them he would soon be wheeled into theatre.

‘Just prepping for the operation now, I feel like s**t, but fingers crossed’.

It comes just 24-hours after Max shared a snap of himself receiving medication as medics prepped him for surgery.

The cause of his illness has been a ‘mystery’ and Max, who has battled alcoholism in the past, previously said: ‘We’ve cancelled out a few things, like alcohol for example I’ve not had a drink for four-and-a-half years so it’s not that’.

It was revealed his girlfriend Maisie Smith has been struggling to juggle performing in a pantomime with seeing him – who is ‘on her mind 24/7’.

An insider told The Sun: ‘It’s been a really worrying and distressing time for Max and Maisie.

‘All she wants to do is be by his bedside day and night but she’s committed to her panto show and doesn’t want to let anyone down.

‘She’s done her best to be able to visit him when hospital visiting hours allow, but it’s been a real struggle juggling everything.

‘Max is on her mind 24/7 and she wants more than anything for him to be better as soon as possible.’

A representative for Maisie declined to comment when contacted by MailOnline.
