“@olympiaohanian & I wanted to welcome her back to tennis. Designed them myself, with some help from Jr.,” Ohanian wrote.

Us Weekly reported that the billboards have images of 5-month-old Alexis Olympia Ohanian Jr. and her mother with the words "Greatest Momma of All Time." The last billboard forms the acronym G.M.O.A.T.

Williams, who is competing in the 2018 BNP Paribas Open in March, saw the billboards as she traveled to Indian Wells, California, on Monday, according to Us Weekly. From Feb. 10-11, she competed with sister Venus Williams at a doubles match in Nashville, North Carolina, at the Fed Cup. Little Alexis and Ohanian were photographed looking on during the first round. The Williams sisters lost to Lesley Kerkhove and Demi Schuurs.
