Former top-ranked women's tennis player Naomi Osaka has given birth to her first child, a girl, according to a report Tuesday on the International Olympic Committee's website.

The 25-year-old, a two-time winner of both the U.S. Open and Australian Open, announced her pregnancy in January on social media. Her partner, popular rapper Cordae, revealed the news of the birth during a performance in Canada.

The couple said that Osaka was expecting a baby on social media in January. In June, Osaka revealed she was expecting a girl with a princess-themed baby shower.

Osaka has not competed on tour since withdrawing from an event in September due to lower back pain and is currently ranked 436th in the world.

She has stated her intention to compete at next year's Australian Open and to represent Japan at the 2024 Paris Olympics.

Osaka won her first major tennis crown at the 2018 U.S. Open and then captured the 2019 Australian Open. She followed that with another pair of back-to-back Grand Slam singles titles at the 2020 U.S. Open and 2021 Australian Open.
