Former Hills star Heidi has been desperate for a baby for several years and, last month, she revealed husband Spencer Pratt was finally ready to start trying.
The couple are hoping to have their first child together before Heidi turns 29 next year and she is already checking her ovulation pattern with test sticks.
But could the magic have already happened?
Last night, Heidi shared the snap of herself outside a shop which sells clothes and accessories for babies. She simply said: "Baby store!"
Earlier this week, Heidi also posted a generic shot of a sleeping tot, adding: "What I'm asking Santa for Christmas!"
Heidi and Spencer, who starred on MTV's The Hills together, married in 2009. Spencer, however, has not felt ready to become a dad until now.
In an interview with American magazine Life & Style, Heidi revealed: "Last year, while we filmed an E! special, he told me, 'I don't want to have kids,' and I started crying.
"I told him I couldn't bear the thought of never becoming a mum. So when he saw how important it was to me, he had a change of heart."
Fingers crossed you'll be a mum soon, Heidi!
