Chrissy Teigen hates wearing undies

Chrissy Teigen's fiance John Legend revealed during the TMI-fest that the Sports Illustrated Swimsuit model does not like wearing underwear.

Legend told her 'Fashion Police' co-panellists that she doesn't wear underwear, which led Joan Rivers to ask her if she was wearing any at that time, stuff.co.nz reported.

Teigen replied that she wasn't wearing 'any.'

When she was asked why she didn't wear underwear, she quipped that she didn't like it.

Rivers then asked Teigen what she does when it's her time of the month.

Teigen replied that the string then goes in her b*** crack.
