 Serena Williams Writes Touching Message to Baby 
 
 Breaking News 
 
 Serena Williams is opening up about her pregnancy -- with an emotional message to her unborn child describing how the experience is changing her life. 
 
 "My Dearest Baby, You gave me the strength I didn’t know I had," Williams writes. 
 
 "You taught me the true meaning of serenity and peace. I can't wait to meet you." 
 
 She also mentions the fact she's moved back to #1 on the newest WTA rankings -- a ranking list that happened to be released on her fiancee's birthday. 
 
 "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 [Alexis Ohanian's] bday. from the world's oldest number one to the world's youngest number one. -Your Mommy."
– It's been a busy few months for Serena Williams. First the tennis star announced in December she was marrying Reddit co-founder Alexis Ohanian, then she won the Australian Open, and finally, the biggest news of all last week: She's pregnant. Now TMZ reports that Williams is opening up a little more than the original cryptic Snapchat post that alluded to her pregnancy. In a Monday morning Instagram post addressed to "My Dearest Baby," a smiling Williams says she "can't wait" to meet her little one, that the baby inside her has given her "strength I didn't know I had," and that "you taught me the true meaning of serenity and peace." She closes out her note "from the world's oldest number one to the world's youngest number one" and signs it, simply, "Your Mommy." Cue Twitter's tears. (Another tennis star's reaction to Williams' pregnancy was … unfortunate.)
