The former TOWIE star, who is currently expecting with boyfriend Paul Knightley, spilled all on her due date, while sharing a baby bump update with fans.
Already looking like she is ready to pop, Sam is now sporting a huge bump as she prepares to welcome her new arrival.
Taking to Instagram, Sam can be seen glowing as she posed in her all-in-one for the snap. And proving she hasn't been taking a break while expecting, the 24-year-old hinted she has been working on maternity fashion range.
Alongside her post, she told fans: "Cosy at home #nesting less than 4 weeks to go if our little one comes on time wearing my maternity jumpsuit I designed.. Available to buy this week. I will keep you mums to be posted."
Sam's latest Instagram comes as she prepares to give birth in January. She first announced she was pregnant back in August and has since kept fans updated with plenty of pictures of her growing tum.
She and Paul have decided not to find out the gender of their unborn baby, keeping it as a surprise for when their little one finally arrives.
This will be the couple's first child first together. Sam and Paul have been dating for over a year now, but only went public with their relationship in April.
Gushing about her beau recently, Sam told Paul she thinks he is going to make the "most amazing daddy". N'aww.
