The mum-of-one showed off her svelte figure in leather-look trousers and a black draped blouse as she walked the red carpet at London's Saatchi Gallery on Thursday 5 November.
Adding a splash of colour to her already chic ensemble, Nadine finished off her look with some orange pointed suede heels.
Following on from President Xi's recent visit to the UK, the Saatchi Gallery has hosted a Chinese art exhibition series, and created by a number of prominent artists and curators.
The night was to celebrate British and Chinese culture through art, and it looks like Nadine may have got some inspiration from it too.
"The exhibition was wonderful and it was great to attend the opening night," she said. "Some of the art would be perfect on my walls!"
While Nadine was at the art exhibition, her former Girls Aloud bandmates Nicola Roberts and Cheryl Fernandez-Versini supported Kimberley Walsh at the press launch of her new musical Elf, in which she plays Jovie.
