"Well someone is going to be a big sister next year! We're so excited to share with y'all that I'm expecting again!" Geary captioned the post.
"We find out Saturday if it's a boy or a girl! What do you guys think it's going to be? Forgot to mention the due date is Robins birthday!" she added. Thicke turns 42 on March 10.
