The Atomic Kitten star is expecting her fifth child and looked gorgeous in a pale peach, floor-length gown with bead embellishments.
Natasha was snapped at Lorraine's High Street Fashion Awards and, coincidentally, her outfit was from the high street!
The singer's dress is from Topshop although it is from a past season, meaning fans can no longer get their mitts on it. Boo!
Natasha was joined by her Atomic Kitten bandmate Liz McClarnon at the event and together they presented the award for Most Affordable Fashion to Primark.
After the event, which was held at Vinopolis in London, Natasha tweeted: "Just had a fab time presenting best high street fashion at the @lorraine HSFA2014 #watchitwearitownit wearing @topshop."
Last month, Natasha and her boyfriend, 5ive star Ritchie Neville, revealed that they are expecting their first baby together.
Since then, Natasha has shared a cute scan picture of their unborn child.
Meanwhile, Natasha wasn't the only pregnant celeb gracing the red carpet last night.
Girls Aloud singer Kimberley Walsh was pictured at Lorraine's High Street Fashion Awards in a figure-hugging monochrome dress.
