Rihanna, Pharrell Williams and Justin Timberlake lead tributes for Muhammad Ali

The boxing legend has passed away, aged 74

Today the world mourns legendary boxer Muhammad Ali, who died on June 4, aged 74.

The athlete famously suffered from Parkinson’s disease which he battled for the last 32 years of his life. The star died in Phoenix, Arizona after being admitted to hospital on Thursday with respiratory problems.

Ali, born Cassius Marcellus Clay Jr., was considered by many to be the greatest heavyweight boxer in history. He remains the only three-time lineal heavyweight champion of the world, taking home the title in 1964, 1974 and 1978.

The boxer, often known simply as ‘The Greatest’, leaves behind nine children – seven daughters and two sons – from his four marriages.

One of the last tweets Ali shared was a tribute to Prince who died on April 21 of this year.

Fellow boxers Mike Tyson and Oscar De La Hoya paid tribute to Ali with these Tweets.

Snoop Dogg is also one of many stars to pay tribute to the late boxer with this picture of the pair of them on his Instagram page.
