Serena Williams is making her much-anticipated return to tennis. She took time off last year to give birth to her daughter Alexis Olympia. Williams will return for the BNP Paribas Open, which begins March 5th. It's her first tournament since winning the 2017 Australian Open. Her husband, Alexis Ohanian, is thrilled for her return to tennis. He's so excited that he bought four billboards to celebrate. The billboards spell out "Greatest Momma of All Time Serena Williams."
