The 'Your Love' singer was spotted leaving the Radio 1 studios flashing more than a hint of flesh as she sauntered down the pavement.
Brunette beauty Nicole wore a black short-sleeved shirt but only did up the top button, allowing her racy bra to show through underneath. Maybe she forgot about the other buttons?!
The songstress also flashed her toned midriff as her shirt blew in the wind, accessorising with a statement necklace by Misahara, black lacquered nails and heaps of statement gold rings.
Nicole took a tip from the fash pack by rocking this season's ripped jeans trend, opting for a faded dark-wash pair with frayed tears just above the knees.
She topped her lengthy pins with pointed black heels while shielding her peepers with cat eye sunnies, styling her flowing brunette locks in loose, tousled waves.
Now we're not too sure why Nicole chose to flash so much skin in her unbuttoned shirt, but it seems she's been on a bit of a role with her revealing outfits lately.
Just this weekend Nicole stepped out for dinner in London while flaunting her silk bra in a plunging low-armhole top.
Former X Factor judge Nicole also showed off her svelte silhouette by doing the ALS Ice Bucket Challenge in a teeny bikini. This girl's got guts!
