Spears and songwriter Sia Furler have been teasing the new song's title by using the hashtag #WERK in their tweets.
Britney Spears' upcoming new single is reportedly called "Werk B**tch". Fans site BreathHeavy has claimed that the song will be released as the lead single off Spears' eighth studio album, which is currently still in the works.
Spears hasn't said a word about the title for her new single. However, Jean Baptiste, who has worked with the 31-year-old singer on her new record, appeared to confirm the rumored title, tweeting, "WERK B**CH!!!!".
Spears and Sia Furler, the songwriter she has been working with, have both recently teased the title by using the hashtag #WERK in their tweets.
Last week, Spears took to Twitter to inform her fans that she was working on something "top secret." Spears' publicist then revealed that the former Disney star had "been using a vocal coach and going to regular sessions and also been working hard with her choreographer" for the mysterious project.
