The Saturdays took to the Virgin Media Stage during day one of the V Festival at Hylands Park in Essex this weekend - and it was Mollie who really stood out in her barely-there fringed bra top and high-waisted Topshop denim shorts.
They've been staying in a luxury VIP area, complete with double beds and Egyptian cotton sheets, reports the Daily Mail.
But mum-to-be Frankie Sandford had to sit this one out, and won't be joining the girls on stage again until she's welcomed her little one.
