A source tells ET the singer is 'really focused on working on her new music right now.'
When it comes to Fourth of July parties, no one does it better than Taylor Swift!
Over the past few years, the 27-year-old pop star has hosted epic Independence Day bashes at her Rhode Island mansion, inviting a slew of A-listers and making headlines with their enviable Instagram posts. But on Tuesday, Swift and her famous squad were nowhere to be seen at the multimillion-dollar beachfront home.
Although an inflatable slide was set up on the property, the only people reportedly spending time at the estate this week were the singer's parents, Scott and Andrea Swift.
So how exactly did Swift and her celeb pals celebrate?
No official word on exactly where Swift was on Tuesday, but fans were hoping to catch a glimpse of her hanging out with her rumored new boyfriend, Joe Alwyn. The two have kept an extremely low profile since romance rumors began swirling in May, a drastic difference from her whirlwind romance with ex-boyfriend Tom Hiddleston. Who could forget last year's party, in which the Thor star wore an "I Heart T.S." T-shirt?
A source told ET on Wednesday that although they don't know why Swift didn't hold her annual bash, the blond beauty is "really focused on working on her new music" right now. The source also told ET the singer is "just in focus mode."

"She's spending time with her family ... just doing her," the source added.
As for Swift's relationship with Alwyn, the source believes the Reading, Pennsylvania, native is keeping their love on lockdown in hopes of avoiding the media attention she's received with previous romances.
Despite Swift's decision not to have a party this year, that didn't stop her famous friends from celebrating. Cara Delevingne and Karlie Kloss spent the holiday in Paris, France, with Kendall Jenner and Derek Blasberg, who were all in town for Paris Fashion Week.
They were later joined by Swift's frenemy, Katy Perry, who pulled out all the stops with her red, white and blue-themed ensemble.
