Patriotic Celebrities: Stars Show American Spirit (PHOTOS)

Memorial Day may evoke thoughts of barbecues and pool parties, but it's also a time to show some American pride and remember those who have served and are currently serving the U.S., both at home and abroad. And for their part, some celebrities just love to sport some red, white and blue.

Katy Perry is no stranger to star-spangled style -- she looks particularly nice in a certain blue sparkly ensemble -- and she's not alone in her patriotism. Singer Ke$ha, who even rocks an American dollar sign in her stage name, isn't shy about showing her stars and stripes, both onstage and on magazine covers.

But it's not only Americans who are rocking the red, white and blue. Brits Rosie Huntington-Whitely and Craig David have been spotted sporting American flag fashion at times.
