John Legend’s wife accidentally flashes her 'nunu' after suffering a horrible wardrobe malfunction (Photos)

Drake, Ariana Grande, Rihanna, Justin Bieber and Enrique Iglesias were among the big winners of the night, but all-eyes were on Chrissy Tiegen’s fashion fail which quickly became the most memorable moment of the night.

John Legend’s wife decided to step out in an audacious black dress that showed off acres of thighs and was held chaotically together by a few pins. Her dress proved to be a terrible idea after she flashed her knicker-less crotch much to the shock of all those that watched her.

The only redeemable quality about her outfit was her shoes which looked like Giuseppe Zanoti lace-up sandals. Her flawless make-up and her sleek and straight hairstyle were to die for too but the ghastly dress just seemed to take centre stage with all the crotch-flashing.

The night however was not a total loss for Tiegen and she salvaged it by leaving all the viewers teary-eyed as she gushed about her husband John Legend.

This was after stepping on the AMA stage to introduce her husband who was performing his hit single ‘Love Me Now’ which already has more than 16 Million views on You Tube.

“So this next performer is a brilliant musician and a wonderful father, who makes a pretty d**n good breakfast sandwich... Performing his new single, Love Me Now, please welcome the love of my life - John Legend." She said as the crowd cheered her husband on to the stage.
