Chelsea striker Sam Kerr and West Ham midfielder Kristie Mewis are expecting a baby next year.
Australia captain Kerr, 31, and 33-year-old Mewis announced the news on Kerr's Instagram account in a post which read: "Mewis-Kerr baby coming 2025!"
Mewis will carry the baby.
"A huge congratulations to Kristie and her partner Sam, who have announced they are expecting their first child," West Ham said on Instagram.
Kerr is Australia's record goalscorer and one of the country's biggest sporting idols.
She has won five consecutive Women's Super League titles, three FA Cups, two League Cups and the Community Shield at Chelsea.
She signed a new two-year contract in June but has not played since January because of a knee ligament injury.
Mewis, who has won 53 caps for the USA, joined West Ham from NJ/NY Gotham FC in December.
In March Kerr pleaded not guilty after being charged with racially aggravated harassment of a police officer in London. She is scheduled to appear in court in February.
