The Irish singer is expecting her first child with former fiancé Jason Bell and announced her happy news in August, just months after she'd finished her final tour with Girls Aloud.
Earlier today (17 October), the yummy mummy-to-be proved that although she has a large bump to dress now, her style is still as trendy as ever.
She was spotted out and about in the capital wearing a comfy cream cardigan, which she layered over a light blue denim shirt and terracotta coloured jeans.
Nadine, 28, also made sure she was extra comfortable by swapping her glam heels for a pair of fluffy Ugg-style boots and completed her look with a large brimmed hat, a cream handbag and a pair of sunnies.
It is thought that the pop star is heading back to Los Angeles this week, where she now lives with ex American footballer Jason.
Although she and her beau have a long history together and first began dating in 2008, it was not clear who the father of Nadine's child was when she announced her pregnancy in the summer.
Since there was no news of the couple reconciling after their split in 2011, Nadine was compelled to confirm that she was expecting Jason's baby earlier this week.
"This clears it up!", she said in a recent interview.
