Johnson confirms that they're planning for Fifty Shades of Grey sequels, which gave Letterman an idea. "They should bring back the first guy for the second film," the Late Show host suggests. "I bet his schedule has opened up now!"
The Fifty Shades of Grey talk doesn't stop there. In fact, Johnson makes Letterman blush! The actress tells the host that her mom, Melanie Griffith, instructed her to tell him that she loves him. "She really meant it!" Johnson muses.
