American tennis super star Serena Williams will not celebrate her daughter, Alexis Olympia's first birthday next month because she is a Jehovah's Witness. Asked how she would be celebrating her daughter's birthday at a press conference at the US Open on Monday, Serena said: "Olympia doesn't celebrate birthdays. We're Jehovah's Witnesses, so we don't do that."

Jehovah's Witnesses, a breakaway sect of Christianity, do not celebrate religious holidays such as Christmas and Easter, and do not celebrate birthdays either. They believe that these festivals have pagan origins.
