Rochelle Humes, Vanessa White, Mollie King and Una Foden (nee Healy) kept all eyes on them at the Westfield London shopping centre during an event for Nokia Lumia and Carphone Warehouse on Monday evening (4 November).
Fifth bandmember Frankie Sandford is on maternity leave following the birth of her son Parker.
At the photocall yesterday, the band met fans and also launched a competition to allow a select handful of lucky people the chance to watch them at a very, very private concert in February. In fact, only twenty winners will be in attendance!
The Saturdays have been busier than ever lately promoting brand new album Living For The Weekend, which features the fab singles 'Disco Love', 'Gentleman' and 'What About Us'.
They've also been working on plenty of side projects. Rochelle is a team captain for BBC Three panel show Sweat The Small Stuff and recently co-hosted This Morning for a second time with husband Marvin. She's also playing mum to adorable baby Alaia-Mai, born in May.
Mollie, meanwhile, has launched her own fashion range for Oasis, signed as a model and been the face of Maybelline, while Una is mum to daughter Aoife Belle and has landed a presenting role on children's TV for Irish network RTE.
Later this week, the band will travel to Bristol to turn on the Christmas lights at The Mall and launch its Winter Wonderland. They'll also be performing 'Disco Love' at the event, which is expected to attract 10,000 people.
