The Atomic Kitten star shared the joyous moment on Twitter today (April 15), telling her followers: "So....just had my tummy examined & I just felt the baby move, or should I say kick for the 1st time!:) so happy right now, all is good x."
This is 31-year-old Natasha's first baby with 5ive star Richie Neville. The pair began dating after getting together on Channel 5's The Big Reunion last year and earlier this month announced they are expecting a baby together.
While it's the first child for Ritchie, 34, this baby is the fourth for Natasha. Natasha is already mum to sons Josh, 11, Harry, eight, and Alfie, three, from previous relationships.
Speaking about Richie, Natasha recently told Reveal: "He's great with the boys anyway and he wants to know everything about pregnancy. He's got the biggest pile of pregnancy books!
"He's been asking me loads of questions, and I've been making him watch One Born Every Minute so he's ready for it. He just cannot wait."
