Uber-private Shania Twain just found a secret hideaway.

The singer and her even more reclusive husband, Robert (Mutt) Lange, took a villa on Mustique, the tony private Caribbean island with 85 mansions on it, some home to Mick Jagger, Tommy Hilfiger, and Maxim publisher Felix Dennis. Shania chose a secluded five-bedroom estate on which the living room floats atop an "infinity pool," where the water's edge appears to pour into the sea.
