She had never danced before Singing in the Rain, and she had never kissed, either.
She had to be shown how to kiss and be kissed, she recalls, and I won’t tell that entire story, because I don’t want to steal the thunder of the Hollywood legend whose memoir I am currently writing. Instead, that legend gave her a lesson, she said it took just a few minutes, and he claims that it went on for hours in how to kiss. Thus she was ready, or so she thought, for the moment when Gene Kelly would embrace her. To her shock and horror, Kelly not only kissed her once the cameras rolled, but jammed his tongue down her throat, which she had never expected or heard of. Disgusted, and outraged, she backed off, gagged, shrieked, and ran crying all the way to her dressing room.
Production halted until someone could coax her back to the set. She says that if you take a look at the last scene of the film, you’ll see a mightily annoyed Gene Kelly giving her the tiniest of unromantic, closed-mouth smooches at what should have been the happy triumph of a couple over all manner of Hollywood adversity.
