While you were busy chowing down on cheeseburgers, arguing about politics with family members and almost lighting your backyard on fire with small explosives on July 4, famous people spent the day doing things like throwing epic parties in their Hollywood mansions and showing off their perfect "airbrushed asses" on Instagram.

While she wasn't able to attend her bestie Taylor Swift's over-the-top, reportedly PDA-filled beach house party in Rhode Island, Selena Gomez threw a bash of her own while traveling on tour in Arizona (she performs in Phoenix on July 5).

In a video posted to Instagram, the "Kill 'Em With Kindness" singer walks through a house bustling with guests before launching herself backwards into a pool. #hostessvibes

Booties were another theme — and really, what's more patriotic than butts? — with stars like Hilary Duff, Ariel Winter and Kate Hudson all showing off their behinds for the Fourth of July.

Other celebrities took video clips of themselves waving American flags or U.S.A.-related things, like Reese Witherspoon's red, white and blue pinwheel. Doesn't she look just like the Fourth of July? Makes me want a hot dog real bad.

When it comes to truly enviable July 4th celebrations, however, Miley Cyrus takes the cake: The pop star got an adorable new puppy just in time for the national holiday — a true testament to the Land of the Free, Home of the #Blessed!

Meet her cute new beagle, Barbie, below and see how other celebrities spent their very patriotic days:
