Everyone knows that Taylor Swift throws some of the coolest parties around, and her Billboard Music Awards after-party was no exception! The "Bad Blood" singer hosted her very own stylish soiree and invited tons of celeb guests: including Niall Horan, Louis Tomlinson, Liam Payne, Ed Sheeran and Calvin Harris.
The whole party had a blast posing in a ton of photo booth pics together, complete with fun props and silly facial expressions that we love!
