Mel B has reportedly postponed a 'crucial eye operation'.

The former Spice Girls star underwent a botched medical procedure 15 years ago, severely affecting her vision in one eye.

She's said to have recently undergone tests to see if she would be a good candidate for a corneal transplant; but according to MailOnline, the surgery has been delayed.

Mel opened up about her desire to undergo a corrective procedure just last week.

'I can't see at all out of my left eye. The lasering went wrong so this [operation] will be totally life-changing,' she told Hello! magazine.

'I had laser treatment done to correct [my eyes], but it started to reverse in one eye. It's scary.

'I'm going blind again. I had a bit of a nightmare. I was reading the autocue and then suddenly I realised that I couldn't see properly.'

A spokesperson for the star told the outlet it's simply a matter of logistics.

'She was due to have it [the operation] in LA this week.

'Mel talked about it in the Hello! interview and said she would have the operation as soon as she got back.

'But she hasn't returned to LA, she's still in the UK and she's had to postpone the surgery for now," the rep. said.

News of the delay comes amid rumours of martial turmoil for Mel and husband Stephen Belafonte.

The producer, who has been married to Mel for seven years, has been accused of being unfaithful and abusive.

But Stephen came forward earlier this week insisting he had nothing to do with her bruised appearance on last week's X Factor UK despite salacious claims.

'I had nothing to do with hurting my wife,' Stephen told British newspaper The Sun. 'I did not touch Mel. I didn't hit her. I wasn't cheating or anything. There was no girl involved.'

Mel has yet to directly comment on the claims.
