We are sleepless and delirious but so excited to share that, our miracle baby, arrived last night via surrogate and 11/7 will forever be etched in our hearts as the most loveliest of all the lovely days. Welcome to the party sweet girl! #onelastdance @itsgabrielleu ❤️ ♥️ ♥️ https://t.co/JudAeQlbJ7
The baby was born via surrogate after Union shared her struggle with infertility last year.
Wade and Union have been married since 2014 and are already raising three children—two of Wade's sons from a previous marriage, along with Wade's nephew.
The 36-year-old NBA star returned to the Heat after contemplating retirement this offseason but noted this will be his last season in the league. It will be his 16th campaign, which included 12 All-Star selections and three titles.
