They've been close friends and fellow fashion icons since The Saturdays burst onto the pop scene six years ago.
And it would seem that Una Foden and Vanessa White had swapped style notes as they attended a fan signing event with their bandmates on Monday evening.
Joining Mollie King and Rochelle Humes at Westfield London's Carphone Warehouse, the dazzling duo both opted for prim and pretty pastel ensembles as they hit the store to meet some of their most doting fans.

Una opted for ladylike tailoring in an effortlessly chic baby pink top, which she teamed with flattering grey cigarette pants and a floral statement necklace.
Teetering on black stiletto heels, the 32-year-old singer wore her auburn locks flowing around her shoulders in loose waves as she joined her bandmates in celebration of their latest collaboration with Nokia.
Following her pal's sartorial lead, Vanessa looked equally stylish in a fluffy grey short-sleeved sweater and matching micro-mini, while elongating her petite frame with towering nude heels.
