The Saturdays star Rochelle Wiseman has teased that fans can expect something "different" from their new single.

The girl group are currently working on their fourth studio album, following the release of mini-LP Headlines! last year.

Earlier this week, Wiseman told fans on Twitter: "Heard our new single all finished WOW! You guys are in for a treat!!!! Wooooooo (sic)"

Asked to describe the track during a question and answer session with fans today, she responded: "It's different/fierce."

However, her bandmate Mollie King refused to reveal the song's title, adding: "Not just yet, but stay tuned for news! ahhh exciting."

The 'Higher' group previously confirmed that they will tour again in December following the release of the new album.
