The couple welcomed a baby girl via surrogate on Wednesday night and shared the news on Instagram.
Gabby and Dwayne posted a series of family photos showing the baby all wrapped up in the hospital. Quoting Bill Withers' 1977 hit "Lovely Day," the new parents are beaming with their bundle of joy.
"We are sleepless and delirious but so excited," Gabrielle wrote, calling their baby a "miracle."
Gabby has been very public about her fertility struggles, revealing in her book that she's had "eight or nine" miscarriages.
"11/7 will forever be etched in our hearts as the most loveliest of all the lovely days. Welcome to the party sweet girl," she continued.
This is Dwyane's first daughter -- he's already a father to three sons.
