Victoria Azarenka has given birth to a baby boy, the former world number one announced on Tuesday. 

The Belarusian, a two-time Australian Open champion, revealed back in July that she was expecting her first child.

And the 27-year-old posted on social media that she has given birth to a healthy boy.

She wrote: "Today I had my hardest fight and my very best victory! Our son was born healthy and happy! So thankful and blessed! Thank you."

Azarenka said this month that she wants to return to tennis "as soon as possible" but is not putting a timeframe on her comeback.
