I’ve been a very lucky pal of Dita von Teese this week. First, I saw her perform her infamous feathers and birdcage routine in Sao Paulo. And while we were down there, she said she was doing a surprise appearance a few days later in Brooklyn. Intrigued, I said I’d go. I showed up at the Musical Hall of Williamsburg to discover she was making an expected cameo at a Mika concert. That Mika. So cute and talented. An added thrill? It was the first time that Dita has ever incorporated her voice into a performance. (Burlesque is all about the body, darling.) Mika’s suggestion on Dita’s performance: She leave the Michigan in her voice because, well, you can’t hate a girl with a body like this if she has a voice like that. So, behold Ms. von Teese coming out and taking off as an added visual for Mika’s hit song, Big Girls.
