Dakota Johnson surprises ‘Saturday Night Live’ audiences with a cameo during Lily Allen’s ‘Madeline’ performance. The ‘Fifty Shades of Grey’ actress donned lacy lingerie as she sat on a bed behind a sheer curtain and read ‘Madeline’s messages to Lily. The song, which has the singer confronting a woman for sleeping with her husband, is reportedly based on Lily’s own experience with ex-husband David Harbour. The pair announced their split in February with Lily accusing the ‘Stranger Things’ star of having a three-year affair.
