20 Photos That Prove Taylor Swift Had the Best Weekend Ever

— -- Coming back to work after a holiday weekend is tough.

Judging by the photos from Taylor Swift's July 4 celebration, the singer likely has a serious case of the Mondays.

Swift, 25, hosted a slew of friends at her home in Rhode Island, and the crew posted photos from the bash on Instagram.

Among the familiar faces in the group: Swift's new boyfriend, Calvin Harris, Gigi Hadid and her new beau Joe Jonas, Ed Sheeran, Haim, model Martha Hunt and "Empire" actress Serayah McNeill. During the weekend, the group baked a cake, went for dips in the pool and wore matching onesies provided by Hadid and Jonas.

"Happy 4th from me, @gigihadid, @marhunt, @britmaack, @serayah and @haimtheband :)" Swift wrote on social media.
