Oops! Chrissy Teigen had a NSFW wardrobe malfunction on the red carpet!

Cape Town – Chrissy Teigen had an unfortunate wardrobe malfunction at the American Music Awards on Sunday night.

While musos like Drake and Justin Bieber walked away with a bunch of trophies for their music, Chrissy may have won the prize for most revealing dress on the red carpet.

The 30-year-old wore a black gown with a risqué slit reaching up to her torso on either side. 

While the deep slits were held together with safety pins, Chrissy’s dress turned out to be a lot more revealing as the front of her dress flashed open.

This was definitely the wrong dress not to wear underwear with.

Chrissy accompanied John Legend to the awards show and took to the stage introduce her hubby, who performed his latest hit Love Me Now.
