The Fourth was definitely with Taylor Swift and company in 2015.
The singer - who hosts an annual party in celebration of America's independence - threw it down at her Los Angeles mansion on July 4, cooking for her guests and providing them with the largest inflatable slide we've ever seen.
Boyfriend Calvin Harris was in attendance. So was ex-boyfriend Joe Jonas and his new girlfriend.
What other celebrities rocked a red, white and blue onesie? How did this year's party compare to the party in 2014?
