Mel B was struck down with an eye infection ahead of the first semi-final of 'America's Got Talent' on Tuesday night (01.09.15).

The judge was left with a red and swollen eye ahead of the live show and was worried she wouldn't be able to take her spot on the panel along with Howie Mandel, Howard Stern and Heidi Klum due to the condition.

Mel posted a photo of her infected eye on Instagram, appealing for tips to improve its appearance.

The accompanying caption read: ''Dealing with a really bad eye infection ouch can't believe I'm on live in a few hrs, any suggestions? Glasses, eye patch :( Yes yes I've already been to the dr (sic)''

Mel made sure she kept her eye clean and used sanitiser to keep her hands germ-free after touching the infection to stop it from spreading.

In the end she made the live show but wore sunglasses to cover her eye.

Although she had been feeling miserable about her illness, the former Spice Girls star was cheered up by her daughter Madison - her child with husband Stephen Belafonte - who was celebrating her fourth birthday yesterday.

In more Instagram posts, she said: ''Yep my eye infection was too much to handle so I had to put on ma shades :(

''But birthday girl is keeping me company though awwwww Madison #4yearsoldtoday (sic)''
