In the snap, Tyler wears a black crochet maxidress with sheer details that flatteringly hugs her belly. "Ohhhh my goodness look at that bump so pointy and giant!! I can't wait to meet the beautiful little human living in there," she wrote in the caption.
In addition to showing off her growing bump, the Leftovers star also showcased her latest studded handbag design for Belstaff.
"I designed this handbag for @belstaff," wrote Tyler, who presented her first capsule collection for the British brand earlier this year. "And it will be available soon to buy." Lucky us! The question is what will come first, the bag or the baby?
This is Tyler's third child as she is already mom to sons Milo, 11, and Sailor, 1.
