Serena Williams has gone into labour with her first child, and is expected to give birth today, after being induced last night. 

According to reports, the 35-year-old tennis pro checked in St Mary's Medical Center in Palm Beach, Florida, on Wednesday, with an entire floor of the hospital being cleared in order to ensure the mother-to-be has the maximum amount of privacy possible. 

Serena, who announced her surprise pregnancy with Reddit co-founder Alexis Ohanian, 33, back in April, is reportedly due to give birth on Friday, after doctors made the decision to induce her on Thursday night.
