Tennis legend Serena Williams confirmed she is pregnant with her second child at the Met Gala on Monday.

The 23-time Grand Slam singles champion told reporters at the New York fashion show there were "three of us" on the red carpet when she arrived with her husband Alexis Ohanian.

The couple welcomed their first daughter, Olympia, in October 2017.

Meanwhile, Russian and Belarusian judokas can take part as neutrals at this month's world championships in Doha, the International Judo Federation (IJF) said, prompting Ukraine to pull out of the May 7-14 event in protest.

Ukraine has barred its national sports teams from competing in events that include competitors from Russia and Belarus while Russia's invasion of Ukraine continues.

The International Olympic Committee (IOC) last month recommended that athletes from the two countries be allowed to return to international competition as neutrals, meaning they compete under a neutral flag with no emblem or anthem.
