The Saturdays have revealed that they are working with US producer Rodney Jerkins on new material.

The songwriter has lorded over tracks like Lady Gaga's 'Telephone' and Justin Bieber's 'As Long As You Love Me' in the past and it seems he's set to sprinkle his gold dust over The Saturdays.

The British group revealed on Twitter that they are working on a big sounding song with Jerkins, tweeting:

"Can't believe we're in the studio with the LEGEND that is @RodneyJerkins!! Recording SUCH a massive tune for you all."

They continued: "Just had the brill @Darrein_Safron perform for us at @RodneyJerkins studio. Awesome."

The '30 Days' stars have been in America working on a reality TV show as they attempt to break the States.
