Taylor Swift’s Fourth of July festivities were already in full swing over the weekend, but on Monday, the singer kicked it up a notch by throwing a backyard bash at her Rhode Island home.

In the afternoon, Swift hosted a “hopping party” at her beachside mansion for her group of friends, according to a source.

With songs like Shakira’s “Hips Don’t Lie” blasting, the partygoers took turns sliding down a giant, red, white and blue slide with the words “Taymerica” on the side, and also played a game of football on the lawn.

Swift’s new boyfriend, English actor Tom Hiddleston, was decked out in red, white and blue jumpsuit and was spotted doing flips on the inflatable slide alongside Swift’s brother, Austin. The “Shake It Off” singer also held hands with her bff Karlie Kloss as they jumped down the slide together.

Later in the afternoon, Swift – wearing a one-piece American flag bathing suit – also hit the slide with Hiddleston. The pair went down the slide together holding hands, says the source.

Blake Lively – who’s expecting her second child with her husband Ryan Reynolds – took a break from the activity and chatted on Swift’s porch.

On Sunday, Swift and Hiddleston were spotted in the ocean near her home kissing, hugging and getting cozy in the water alongside her star-studded group of friends.

Hiddleston, 35, wore an “I [heart] T.S.” tank top and sported a faux heart tattoo with a “T” in the middle on his right tricep.

Lively (with her growing bump on display), Reynolds, Este Haim, Gigi Hadid, Jordan Masterson, Kloss, Abigail Anderson, Ruby Rose and her girlfriend Harley Gusman were all also spotted taking a dip in the ocean and posing for group photos.
