"Babygirl, we love you so much already and we just can't wait to meet you this summer!!" Wie wrote in the post.
Wie and West, the son of NBA Hall of Famer Jerry West, got married in August in a Beverly Hills wedding.
The 30-year-old's career has come to a halt due to injuries, as she announced in June she would take the rest of 2019 off to get healthy. The 2014 U.S. Open champion only competed in four events this past year.
However, her personal life appears to be thriving.
