Tennis stars Gael Monfils and Elina Svitolina are expecting a child, with their baby girl due to be born in October.

Monfils is the ATP world number 21, while Ukrainian Svitolina is ranked 27th in the WTA rankings.

On Sunday, the pair, who married in 2021, announced the news on their official Twitter accounts.

"With a heart full of love and happiness, we are delighted to announce that we are expecting a baby girl in October," a post on each of their accounts read.

Svitolina has been outspoken about her opinion on Russian and Belarusian athletes participating on the Tour, in the wake of Russia's invasion of her homeland.

In April, the 27-year-old called for Russian and Belarusian players to be banned from all international tennis events unless they denounce the invasion in Ukraine.

She decided to take a break from tennis in March, citing a back problem.
