The Big Reunion star kept a protective hand on her blossoming baby bump as she walked the red carpet at the Theatre Royal in London's Drury Lane.
Natasha wowed in an off-the-shoulder blue dress that highlighted her bump.
As well as looking totally fab at the ceremony, lucky Natasha had an extra reason to smile - she found herself sitting next to Breaking Bad star Aaron Paul!
"Sat patiently for show to start & only sat behind Jessie from Breaking Bad! #seaofamazingpeep," she tweeted.
The 31-year-old and her partner, Ritchie Neville from band 5ive, are expecting their first child together later this year. Natasha is already mum to sons Harry, Josh and Alfie from previous relationships.
"Ritchie is absolutely chuffed to bits, he's going to be an amazing dad," Natasha told Reveal in April. "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."
Natasha, who is due in September, added: "The baby is going to be a lovely addition to our family."
