Katy Perry brings tiny Aretha hat to inauguration

Back in 2009, Aretha Franklin's enormous, gray hat pretty much overshadowed her inauguration day performance of "My Country, 'Tis of Thee," garnering worldwide admiration for it's rhinestoned pizzazz, a Facebook page and a spot in the Smithsonian.

Katy Perry, who performed at this year's Kids' Inaugural Ball, brought a miniature version of the Aretha's bow to Monday's inauguration day festivities.

"Big inauguration, tiny Aretha hat," the 28-year-old singer tweeted.

Perry spent inauguration day with boyfriend John Mayer, who even took a turn posing with the mini Aretha hat.
