It's our nation's birthday, and to celebrate, we're breaking down some of Hollywood's hottest American-themed looks! Jason Derulo showed off his patriotism during a trip to London in June. The singer donned an American-flag shirt, black pants, and a denim-and-leather jacket. And Carrie Underwood proved that she really is an "all-American girl" when she hit the CMA Fest stage showing off her stars and stripes in a pair of flag-emblazoned jean shorts.
But no one rocks the nation's flag quite like Katy Perry, whose red-white-and-blue outfit is bursting at the seams! The pop princess has used her crazy ensembles to reflect her American pride on several occasions. The "Part of Me" singer showed up in her best thematic attire to perform at the Kids' Inaugural Concert on the Saturday before the official inaugural ceremonies in January.
Check out the vid to see more of Perry's patriotic garb; and for more of the latest in entertainment news, tune in to "omg! Insider" on television tonight.
