The Girls Aloud singer flashed a huge smile for the camera after helping Michael Flatley launch his new extravaganza Lord of the Dance: Dangerous Games on Thursday (21 August).
Nadine - who is mum to baby daughter Anaiya - was ravishing in a chic red jumpsuit and matching red wedges, teamed with glossy curls and flawless make-up.
The 29-year-old singer jetted into London earlier this week ahead of her appearances in Michael Flatley's new show, which opens at the Palladium on 1 September.
She'll play the role of Goddess Erin.
At today's launch, the star couldn't contain her excitement at being involved with the production, saying it was an honour to be invited to join the cast.
"I've been a fan of Michael's and of Lord of the Dance since I first saw it so that's the last twenty years I've been watching everything Michael has done and it just gets better every time," she said, according to Theatre People.
"When we first met and Michael asked me to be part of the show, I couldn't believe it. I was on Cloud 9 - still am. To be here in the London Palladium singing Gerard's songs, to be with such an amazing cast and crew I'm just so delighted and just can't thank you enough Michael for the opportunity."
Dangerous Games runs from 1 September to 25 October.
