Photo: The Saturdays 'All Fired Up' Single Cover

The girls are looking as gorgeous as ever on their new artwork.

The Saturdays have revealed their new single cover for 'All Fired Up'.

Each of The Sats sports a rainbow-coloured lace frock, which is a totally different look to the feisty black outfits they wear in the video.

The girls are hoping for a Vodafone Big Top 40 No. 1 with the new single when it's released on Sunday 4th September.

"The Saturdays are thrilled to unveil the artwork for #AllFiredUp!" they tweeted.

"Check it out!"
