The former X Factor star celebrated model Zara Martin's new line of headphones for Skinnydip, enjoying a girly night out at Paradise by Way of Kensal Green.
Diana loves flaunting her pins in itsy-bitsy shorts and this time was no different, with the songstress sporting a crimson red pair which were decorated with fabric panels for a touch of interest.
The 'Once' singer opted for a matchy-matchy look with a coordinating satin jacket, adding a black crop top to showcase a sliver of her taut tum.
On the accessory front Diana kept things pretty minimal, wearing a long ring pendant necklace and a dainty ring along with a pair of round-toe platform heels.
She kept things low-key on the make-up front too, decorating her peepers with a touch of smoky grey eyeshadow and lashings of mascara, while slicking her pout a pale red hue.
And Diana also flaunted her new blonde locks, after returning to her trademark Goldilocks colour earlier this month (after spending four hours in the salon!). She was previously rocking a vibrant fiery red hue which later faded to a soft shade of peach, but it looks like she's now ditched the rainbow mane for good!
