Mark Wright has revealed he’s heading into hospital for surgery – and he’s less than happy about it.

The Essex boy needs to have an operation on his foot after breaking a bone back in September – which left him sporting a rather large cast.

The former TOWIE star shared the news via a glum-looking selfie on Instagram earlier today, revealing he feared piling on the pounds following the op – and so he was hitting the gym hard.

Alongside a shot of himself pulling a frowning face, Mark wrote: ‘Great morning hospital to be told I have to have an op on my foot. Only thing to do. Hit the gym hard, before being bed bound. Got to lose some before I pile it on.’

Whilst Mark hasn’t yet revealed when the surgery will take place or how long the recovery will take, all we can say is we hope wife Michelle Keegan has the patience of a saint – because, judging from his expression, something tells us Mark won’t make the easiest of patients as he recovers from the op!

And Mark was clearly as good as his word about hitting the gym hard – as a later selfie proved.

Posted two hours after the first (bravo, Mark – we struggle to even make it to 20 minutes on the running machine before we keel over), the snap showed the star looking rather sweaty with his hair stuck to his head.

He captioned the shot: ‘Just absolutely beasted myself !! Feels great !! Ignore the Barnet !!’

Still, we don’t think Mark’s got anything to worry about in the waistband department, what with his Instagram featuring food shots including ‘homemade, carbless lean turkey mince burgers‘ and a healthy-looking stew made by lovely Michelle.
