Alexis Ohanian Made Serena Williams Cry With "Greatest Momma of All Time" Billboards

Serena Williams is one loved mama. Serena's husband, Alexis Ohanian, gave her the ultimate surprise by putting up four billboards featuring their new baby, Alexis Olympia Ohanian Jr., along I-10 in California near Palm Springs. Collectively, the billboards read "greatest momma of all time," and the last one features the acronym: GMOAT. The billboards were a gift from Alexis to mark Serena's return to competitive tennis since becoming a first-time mom. (Click through the Instagram gallery to view them all.)

"I wanted to welcome her back to tennis. Designed them myself, with some help from Jr," Serena's hubby's caption reads. Not only is every regular human swooning over how incredibly thoughtful and adorable this is, but Serena is, too. After seeing the photos, Serena commented, "Literally am crying. This is so sweet. I love you." Further proving that these two are relationship goals, Alexis responded on Instagram, writing, "See you soon, GMOAT."

Alexis, the cofounder of Reddit, recently announced his decision to step down from his job to focus on parenthood. He and baby Olympia supported Serena during her first match as a mom earlier this month. Talk about a supportive family!
