Taylor Swift will host livestream session next Monday

Will Taylor Swift soon be premiering a new single about yet another ex? 

After much anticipation and a bunch of hints posted on Twitter and Instagram last week, the country-pop star finally revealed her big surprise last night, Us Weekly reported. 

The I Knew You Were Trouble singer, 24, has planned to host a special livestream via Yahoo next Monday (Aug 18) at 6am (SG time), during which many fans are hoping she will share details on new music, or even share a sample of what she's been working on. 

Swift took to Twitter with the 'big reveal' at 8pm last night: 

According to the Grammy-winning singer's website, the livestream will take place in New York City. 

But this isn't a first for Swift. 

She has previously hosted an hour-long livestream four years ago when she dropped her third studio album, Speak Now and answered questions from fans and surprised fans when she sang three tracks from the new record.
