Serena Williams can't wait to be a mom. A few days after the superstar tennis champion announced she and fiancé Alexis Ohanian are expecting their first child together, she penned a touching note to her baby on Instagram.
"My Dearest Baby," she captioned a selfie showing off her growing tummy. "You gave me the strength I didn't know I had. You taught me the true meaning of serenity and peace. I can't wait to meet you. I can't wait for you to join the players box next year. But most importantly, I am so happy to share being number one in the world with you.... once again today. On @alexisohanian bday. 😉 from the world's oldest number one to the world's youngest number one. - Your Mommy"
Serena, 35, is currently on a romantic babymoon in Playa del Carmen, Mexico, with the Reddit cofounder, who popped the question back in December. In a now-deleted Snapchat, Serena revealed that she's 20 weeks along, and her rep confirmed to POPSUGAR that she's "expecting a baby this Fall."
