Tennis icon Billie Jean King recently wished on what would have been Muhammad Ali’s 81st birthday. The American boxer, regarded as arguably the greatest to ever grace the sport, had died on June 3, 2016.

Cassius Marcellus Clay Jr., aka Muhammad Ali, was born in Kentucky, United States, in 1942. The American is regularly ranked among the all-time greats of professional boxing.

In 1984, he announced that he had been suffering from Parkinson’s syndrome, which had worsened his health gradually. Following a series of hospital visits due to worsening health, the American breathed his last in 2016.

Jean King, 79, turned to social media to post about the boxer’s 81st birthday. She reminisced about their relationship and revealed how Ali would shower praise on the former American tennis player.

“Today would have been Muhammad Ali’s 81st birthday. Whenever we would run into each other, he would whisper in my ear, ‘Billie Jean, you’re the queen’. He is a legend whose legacy continues today,” Billie Jean King captioned her tweet.
