Muhammed Ali's life to be honoured in Vegas by celebrities

Muhammad Ali lost just once in his seven prizefights in Las Vegas over 19 years. Now, dozens of heavyweight celebrities are back in Sin City to laud a lifetime in the spotlight and join the icon known as "The Greatest" in fighting neurological diseases.

Roughly 2,000 people are expected to attend a swanky gala to celebrate Ali's 70th birthday on Saturday night at the MGM Grand in Las Vegas, the site of most of boxing's major fights the past 20 years. Ali turned 70 last month, celebrating then with another party and fundraiser in his home state of Kentucky.

One of Ali's daughters, Rasheda Ali, says the gala is a chance for friends, family and A-list celebrities who look up to her father to pay respect to his legacy as a humanitarian.
