Carey proceeded to tickle Legend's neck with a big pink feather while performing one of her more sensual songs. And the best part? Teigen was front and center at the show, losing her mind in the best way! It turns out, Teigen is a huge fan and was jumping, screaming, and cheering her husband on the whole time, PopSugar details.
