Some of my favorite moments on Instagram over the years have been following along as my friends and teammates have become parents and share that experience. I can't wait to join in! I am so lucky that I get to be Nicole’s husband and the father of our little girl. ðŸŽ‰". The official Insta-famous baby is on her way!
