Dakota Johnson will get to pop her Saturday Night Live hosting cherry this Saturday when she takes to the famous Studio 8H at 30 Rock. (Reminder: Johnson’s famous father is Don Johnson , who starred in the series for five seasons in the ’80s). From her famous Fifty Shades of Grey lip bite to yet another comment about whether or not mom Melanie Griffith has seen the film, Johnson is cool as a cucumber in the teasers.
