‘The Office’ star John Krasinski and Grammy award winning artist Aimee Mann performed the Christmas classic ‘Winter Wonderland’ live at the Wiltern Theatre in Los Angeles last weekend as part of the singer’s Third Annual Christmas Show. Who knew that John could sing? I just hope that he does his singing as plain old fun and that he isn’t going to come out with an album of his own. I don’t care how good an actor or actress sings. If you’re good at what you do for a living, then stick with it. I don’t want to have another Scarlett Johansson out in the world of music.
