The country and pop singer posted an Instagram photo on Sunday morning, in which she and her friends posed for a "family portrait."
Among Swift's guests are Emma Stone, "Girls" star Lena Dunham, "Hart of Dixie's" Jamie King, indie-pop star Ingrid Michaelson and "Gossip Girl" actress Jessica Szohr.
King, 35, also posted several Instagram videos of the group during the holiday weekend. In one clip, Swift, 24, was seen jumping into a pool on an inflatable turtle. "There is only one ninja turtle in town and that is @taylorswift," King wrote in the video caption.
After the pool-side shenanigans, the girls made their way into the kitchen to bake a patriotic cake - a nod to Swift's idol, Ina Garten - and an apple pie. "We made apple pie because America," the "22" singer captioned her photo.
There is another video showing Michaelson, Dunham and Swift trying to light up their festive sparklers.
Dunham also took to social media on Friday to share her Fourth of July plans. "4th of July is my Coachella," the "Girls" star posted on her Twitter . "Be free, ya noodles!"
Then, it was boat time for the group.
King posted a photo of the guests, including a scruffy-looking Garfield, posing on a boat.
"Portrait of heaven amongst friends. Taylor, Amanda, Ashley, Dan, Austin, Jessica, Jess, Odeya, Andrew, Emma, Colin, Vicky, Simon & Zac. Shot by @kyle_newman," the actress captioned the photo.
