Serena Williams' newborn daughter shares a name with her father, Reddit co-founder Alexis Ohanian, but as the tennis star revealed Thursday, there's also a special secret meaning behind the baby's initials.

Williams was about four weeks pregnant with Alexis Jr. when she won her record-setting 23rd Grand Slam title at the Australian Open in January. She said during a TED Talk in Vancouver that she learned of her pregnancy just two days before the tournament.
