Noah Cyrus and a friend are the main (extremely young) faces of a new clothing line... of children's lingerie!

It's called "Ooh! La, La Couture" and it's pretty much a collection of French Maid outfits. To wit:

This isn't the first time 10-year old Noah has been involved in an age inappropriate activity:

She wore this outfit during a red carpet appearance last year; and more recently sung about getting crunked and brushing her tetth with Jack Daniels.
