Is Serena Williams pregnant?
Fans were shocked in December when Williams announced her engagement to Reddit co-founder Alexis Ohanian, as many didn't even know the pair were dating.
CNN has reached out to reps for Williams, Ohanian and the Women's Tennis Association for comment.
The possibility of a little one immediately sent Twitter into a tizzy, given that Williams' good friend Beyonce is pregnant with twins.
