Céline Dion Goes On

Somewhere in the bowels of Palms Casino Resort, just off the Las Vegas Strip, is a recording studio that has seen countless victories. Michael Jackson recorded tracks for the reissue of his seminal Thriller album here; Lady Gaga recorded Harlequin, the first compelling concept album tied to a Hollywood film in years. One evening in June, though, something even more extraordinary is happening: Céline Dion is doing Pilates. She stands with her leg up on a ballet barre, wearing a nude leotard with a lace-trimmed high neck. The singer is lithe and poised, her hair in a perfect bun, mascara coating her lashes. With ease, she slides her leg along the barre, stretching into a wide split.
