Serena Williams is opting out when it comes to her daughter Olympia Ohanian's upcoming first birthday.
The tennis champion and her husband Alexis are Jehovah's Witnesses.
"Olympia doesn't celebrate birthdays. We're Jehovah's Witnesses so we don't do that."
According to the religion's official website, Jehovah's Witnesses don't celebrate birthdays :
"because we believe that such celebrations displease God. Although the Bible does not explicitly forbid celebrating birthdays, it does help us to reason on key features of these events and understand God’s view of them."
One of the reasons mentioned is the belief that birthdays have pagan roots.
