Tennis Champion Serena Williams has announced she will miss the remainder of the tennis season because she is expecting her first child later this year. A spokeswoman for Williams issued a statement to the media saying Serena is pregnant. The 35-year-old Williams won her 23rd Grand Slam singles title at the Australian Open in January – a little less than 12 weeks ago. She has not competed since, citing a knee injury when withdrawing from tournaments at Indian Wells, California, and Key Biscayne, Florida. Williams announced her engagement to Alexis Ohanian, co-founder of social media outlet Reddit, last December.
