Flirty Frankie Sandford gives a cheeky glimpse of her bra in low-cut top for early morning performance with The Saturdays

They might have been lighting up the television screens in the early hours of the morning, but The Saturdays certainly didn't tone down their outfits for Lorraine on Monday morning.
Frankie Sandford led the way in a daringly low-cut mustard yellow vest top, which gave a hint of her black bra beneath as she performed with the rest of her bandmates.
The 24-year-old singer teamed the top with a pair of black and white checked trousers for the television appearance, finished her ensemble off with coloured, patterned court shoes as the girls belted out their new hit single What About Us.

But Frankie had some competition on the cleavage front from bandmate Vanessa White, who wore a sheer pink vest top for the show.
Concealing her modesty, Vanessa teamed the top with a negilee-style top underneath, and teamed the top with a black pencil skirt, boots and a denim shirt tied around her waist.
Mollie King opted for a more casual look in a pair of short denim dungarees over a white vest top, but added a hint of glamour with her peach and silver sky-high heels.

And Una Healy also opted for a colourful approach in a magenta, long-sleeved playsuit for the performance.
Meanwhile, mother-to-be Rochelle Humes clad her bump in a patterned shirt and peach miniskirt, with striped, pointed court shoes.
Despite having just eight weeks to go until the birth of her first child with her JLS singer husband Marvin Humes, Rochelle did her best to join her bandmates with the energetic performance.

And joining the rest of the group talking to Lorraine Kelly on the sofas, Rochelle was presented with a super-cute onesie bearing the slogan 'Future Popstar' on the front.
The 23-year-old giggled as she was presented with the white babygro, before popping it in her bag to take home.
Speaking earlier in the day on Daybreak, Rochelle had said she is predicted that her baby will be somewhat 'lanky' if it takes after its statuesque parents.

She said: 'The poor thing will be quite lanky I think - the tallies.'
And Frankie added: 'It's going to have the most perfect skin!'
Asked if she gets any special treatment from the rest of the band, Rochelle said: 'I always get the seat, which is great.'
