Serena Williams & Daughter Alexis Olympia Cover Vogue US February 2018, Lensed By Mario Testino

Super talent and athlete Serena Williams covers the February 2018 issue of Vogue US. Baby daughter Alexis Olympia -- called Junior by dad, Reddit co-founder Alexis Ohanian, -- debuts as the youngest Vogue cover girl ever. 

Determined to win 25 Grand Slam victories (she now has 23), Serena was forced to withdraw from the Australian open, due to a host of medical complications associated with her daughter's birth. Vogue covers those events in detail, and they were formidable. The Williams comeback is now scheduled for March, with Serena determined to best Margaret Court's all-time record.

The tennis superstar is instilling her well-documented determination in her four-month-old baby. “Women are sometimes taught not to dream as big as men. I’m so glad I had a daughter. I want to teach her that there are no limits.”

Mario Testino captures the entire Williams gang -- mother, sisters and new husband -- in a giant pajama party. Read the interview.
