Celebrity BFFs Rihanna and Katy Perry proved that great minds think alike when they both sauntered down the red carpet at the 2011 Grammys in pretty white dresses.

Katy wore a silvery white number with a long train and feathered white wings while RiRi turned heads in a sheer white gown from Jean Paul Gaultier. Both dresses were over-the-top and super sexy but only one woman can come out as the victor in this white dress battle.

So, who wore white better: Rihanna or Katy? Share your thoughts in the comments!
