Now this is an unexpected but welcome surprise!
Girls' Generation's Taeyeon has announced that she will be releasing a surprise new single on November 1 titled "11:11"! The song is said to be an acoustic pop ballad, and is all about a girl reminiscing about making wishes with her parted lover when the time is 11:11.
As well as the surprise single announcement, Taeyeon has also released two new teaser images, both of which show the singer sporting a darker hair colour than the blonde look we've seen this year.
