The former Girls Aloud star, 29, flew over from her home in LA earlier this week and has since been spotted in an array of stunning outfits.
Friday night (22 August) was no exception, as the singer rocked a chic black dress for her appearance on Saturday Night With Miriam at Dublin's RTE studios.
Looking stylish and immaculately groomed, Nadine's LBD with silver zip down the front showed off her ever-slim post-baby body and famously long legs.
Girl crush alert!
Derry-born Nadine made sure she chatted to fans as she left the studio, and flashed her big smile in plenty of selfies on their camera phones.
Since moving to LA a few years ago, Nadine has kept a relatively low profile.
Nadine became a mum for the first time in February when she and fiancé Jason Bell welcomed their adorable little daughter Anaiya.
Last year, she revealed she was back in the studio working on new music, following her 2010 debut solo album, Insatiable.
The good news for her fans is that Nadine will be spending more time in London in the coming months after taking on a singing part in Michael Flatley's new show Lord Of The Dance: Dangerous Games.
It's good to have you back, Nadine!
