US tennis star Serena Williams revealed her daughter is taking baby steps towards learning her mum's sport. The 23-time Grand Slam champion, who has a daughter, Olympia, three, with entrepreneur Alexis Ohanian, was quick to clarify that she is not one who will be training her kid.

"I signed Olympia up for tennis lessons. Don't even start with me because I'm not giving her tennis lessons, I signed her up for some," Serena Instagrammed. "But the lady has no idea that it's my daughter, so we'll see how that goes."
