Four-time Grand Slam champion Naomi Osaka sported an all-red look with roses for her first US Open match, including a Labubu accessory called "Billie Jean Bling."

Naomi Osaka is bringing the Labubu craze to the US Open. For her opening match on Tuesday, Aug. 26, the 27-year-old tennis star faced off against Greet Minnen at New York City's Louis Armstrong Stadium wearing an elaborate crystal-covered ensemble.

While her tennis shone in her first-round US Open victory on Tuesday, it was Naomi Osaka’s outfit – and Labubu accoutrement – which really sparkled in New York.
