She posted a video of herself walking through what appears to be her crowded house in royal blue booty shorts and a matching blue swimsuit top. As she passes through the masses of people, Selena finally turns and faces the camera before falling backwards into her pool. “Hostess vibes. Happy 4th everyone!” she captioned the Instagram clip.
The background music to Gomez's Snapchat also happened to be Swift frenemy Katy Perry's holiday jam, "Firework."
She also shared a pic of herself emerging from the water at sunset and a funny photo of her with actress Francia Raisa goofing off at a gas station later in the evening.
According to Francia’s Snapchat, the party was a blast. The pals all lit sparklers, danced in their swimsuits, and made it rain dollar bills.
Selena is currently traveling the country on her Revival Tour, last stopping in Denver, Colorado on July 2 before hitting Phoenix, Arizona on Tuesday.
Meanwhile, in Rhode Island, Tay and her new boyfriend, Tom Hiddleston, heated up the Atlantic with a slew of celeb pals.
The “Blank Space” singer posted a photo with stars Blake Lively, Cara Delevingne, Gigi Hadid, Uzo Aduba, Ruby Rose, Halston Sage and more. She was also spotted frolicking in the waves with her new sexy stud, who wore an “I [Heart] T.S.” tank top.
