Dakota Johnson turned up the heat for a steamy Calvin Klein ad. Johnson, 36, went topless as she showed off her Calvins in a sexy campaign that launched on Monday, March 9. In one pic, she ditched her top while wearing nothing but a pair of blue jeans. The actress climbed on top of a piano and leaned on her arms while flashing just the right amount of sideboob. Johnson rocked a pair of baggy jeans and completed her look with a black belt. She went barefoot and displayed her fine line star and "look at the moon" tattoos.
