Shania Twain with a glittery smile at the MGM Grand

Shania Twain offers a winning smile for photographers at the 42nd Annual American Country Music (ACM) Awards. This happened on May 15, 2007 outside the MGM Grand Hotel and Casino in Las Vegas, Nevada. (The photo happened outside; the awards were held inside, of course.) Shania Twain is wearing that mysterious and attractive glitter powder that some celebrities wear at moments like this, and it does look pretty cool.
