They were left wondering whether her accounts had been hacked, whether she was reinventing herself or whether there was a new album on its way.
In addition to Facebook, Twitter, Instagram and Tumblr, her website went dark and the hashtag "TS6IsComing" - as in her sixth studio album - trended worldwide. As The Verge noted Swift's Twitter account appeared to be following the account of her long-term nemesis Katy Perry on Friday; Pop Crave tweeted out a screenshot as proof and then deleted it, per The Verge.
The 27-year-old singer's website taylorswift.com features a black screen. While some posts have been re-posted, her accounts are devoid of profile photos or even a current post to explain what's going on. Radiohead pulled off a similar stunt back in May of this year before announcing they were releasing their new album and some fans are convinced that Swift is following their example.
Swift released "1989" back in October 2014, and the album saw a clear shift in genre. However, fans were taken aback when they noticed that the star had deleted nearly all of her social media.
Swift had counter-sued Mueller in the civil case, alleging he groped her during a 2013 backstage photo op with fans and guests before a concert in 2013.
Another tweeted: "Ladies and gentlemen, Taylor Swift has broke the Internet". Mueller was ordered to pay her a symbolic $1 settlement.
Her profile pictures were also removed. As diehard Swifty fans know, 13 is her lucky number and she often incorporates it into her release dates, music and more.
