On David Letterman’s first show after confessing to affairs with staffers, who should turn up on the couch (upright!) but Glee star Lea Michele. The Broadway fave looked gorgeous in a skin-tight dress, though Dave obviously had no idea who she is. He gamely made conversation about Lea’s Broadway debut at age eight in Les Miz and joked about her youth (watch it, Dave!) and the plot of Glee. Toward the end of the October 5 segment, Letterman perked up when Lea began discussing her tattoos, two of which are on her feet, with a third in an undisclosed location.
