PIC: Did Chrissy Teigen just challenge Instagram with John Legend's butt?!

Cape Town – Since Justin Bieber’s naked pic on Instagram, Chrissy Teigen has now too showed off her husband’s crack.

The Sports Illustrated model posted a picture of John Legend’s nude back but showed only a small fraction of his derriere as her knee managed to leave the rest to the imagination.

Tagging Instagram it seems Chrissy is challenging the social networking site to see if they will take it down or leave it up.

This comes after the 29-year-old posted a picture baring her nipples that Instagram took down provoking her to do it again and again and again. Instagram however won in the end by continuously removing the pictures.

Chrissy’s last attempt was a picture that showed all boob but no nipple. At least Instagram let her keep that one.
