Photos: Alexis Ohanian welcomes wifey, Serena Williams back to tennis with billboards on the highway

Serena Williams is set to play in her first Women's Tennis Association event since giving birth to Alexis Olympia Jr. And the tennis pro's husband Alexis Ohanian surprised her with four billboards alongside the 1-10 freeway into Palm Springs days before the tournament's kickoff.

The billboards, which read 'Greatest Momma Of All Time,' also featured oversized images of their five month-old daughter with Serena, 36. The incredibly sweet tribute was seen by Serena as she made her way to the 2018 BNP Paribas Open in Indian Wells, California. Ohanian is a Cofounder at Initalized Capital, which invests in AdQuick, an outdoor advertising company, which makes it easier for him to do things like this.
