Rochelle Humes, Mollie King, Vanessa White and Una Healy looked as fab as always as they entertained the crowds with some of their biggest hits at Cofton Park on Sunday (1 September).
New mum Rochelle looked smokin' hot in her black dress with a vibrant print detail, teamed with a cropped denim jacket featuring pink trimming, while Mollie showed off her trim waist in a crop top and high-waisted denim shorts.
Also loving the shorts was Vanessa, who gave her look a glam rock edge by teaming them with a black T-shirt emblazoned with the word 'Fade'.
Mum-of-one Una went for maximum colour in a printed bustier top and feathered purple and pink skirt. (Is that the matching skirt for Mollie's crop top?!) Probably not a combination we could pull off but Una looks a-mazing.
They certainly make a glam bunch, don't they? Although, it seems, life as a popstar maybe isn't that different to ours!
After the show, Mollie tweeted: "Great show Fusion Festival! On my way home now looking forward to some X Factor & cup of tea! Loving having @MrsSOsbourne back!! #Originals."
Thousands of fans attended the first-ever two-day Fusion Festival, which featured other acts including Jessie J, JLS, The Wanted, McFly and Amelia Lily.
It's been a busy time for The Saturdays, who are currently performing without Frankie Sandford as she's on maternity leave ahead of the birth of her first child.
They just released the music video for their new track 'Disco Love', which is available 6 October.
