(Can you say "yowza"?) Meanwhile, 26-year-old “Diamonds” singer Rihanna sparkled in a white hot gown from the Tom Ford spring 2015 collection, which highlighed a thigh-high slit and a sheer bra top with purple embellishments that accentuated her assets.

The prize? A print of a nude woman by photographer McGinley, which sold for $300,000.
