Serena Williams won the ASB Classic in Auckland, New Zealand.
This is her first tennis title since becoming a mom three years ago.
She won her last title back in January 2017 when she was actually pregnant with her daughter.
After winning she announced she will donate her earnings of $43,000 in prize money to the Australian bushfire relief.
This Wednesday she will join Roger Federer and Rafael Nadal to play in a charity match that will raise funds to combat the fires.
