The Atomic Kitten star posed with a protective hand on her bump while attending the launch of Joolz new designer custom buggy in London on Thursday (24 April).
'Whole Again' singer Natasha announced earlier this month that she and 5ive star Ritchie Neville are expecting their first child together.
Natasha, 31, later told Reveal the pregnancy was a "very happy surprise", adding: "Ritchie is absolutely chuffed to bits, he's going to be an amazing dad."
Although she's expecting, it doesn't seem Natasha's going to be putting her feet up anytime soon!
She tweeted earlier today: "Just spent the morning at the US embassy to get an iVisa, and it's approved - whoop whoop! America here I come."
Ooh exciting! So far, she hasn't spilled what she's planning to do Stateside or when she's going, although she was quick to assure one follower it doesn't mean the end of Atomic Kitten.
"We are gigging up until end if summer and there's bits in the pipeline," she tweeted.
Natasha's main focus right now, however, is her baby. While it's her first with Ritchie, it will be her fourth child. She's already mum to sons Josh, 11, Harry, eight, and Alfie, three from previous relationships.
Chatting on ITV's Lorraine this week, she admitted her sons are hoping for a little sister.
