The former Girls Aloud star was all smiles as she left the private members club on Thursday evening (28 August), clad in a billowing black coat.
Nadine's huge coat made it tricky to work out what she'd worn for her girls' night out but we think we can spy a patterned skirt, black fitted top and, of course, those unusual white heels.
But let's face it, no matter what Nadine wears she looks amazing, right?!
Clearly it was a fun night as Nadine couldn't wipe the smile from her face as she climbed into a taxi with her friends. And why not? It's been a pretty a-mazing year for the Northern Irish singer so far!
Not only did she become a mother to beautiful daughter Anaiya, she's landed a role alongside Michael Flatley in his new extravaganza Lord of the Dance: Dangerous Games.
There's also rumours of a wedding to long-time partner Jason Bell, the father of baby Anaiya.
She said recently: "Wedding bliss for me? My sister's getting married so it's not all about me. It's all about my sister's wedding. And we're getting dresses and venues and caterers, so it's all about my sister now and then I'll think about getting married one of these days. Maybe."
