Muhammad Ali is coming home to Louisville to celebrate another milestone — his 70th birthday. The iconic heavyweight boxing champion will bask in the limelight once again at a private birthday bash on the evening of Jan. 14 at the Muhammad Ali Center in downtown Louisville. Ali turns 70 on Jan. 17. The party will double as a fundraiser for the center — a cultural and education complex that also features a museum focusing on Ali's long career as a boxer, social activist and humanitarian. “Louisville was the first to support Muhammad in his pursuit of gold,” Lonnie Ali, the boxer's wife, said in a statement Saturday evening. “It is only fitting that Louisville and surrounding communities participate in this important celebration to mark his 70th birthday.” Ali Center spokeswoman Jeanie Kahnke said Saturday that Ali will be surrounded by old friends and people who made a difference in his life, including his longtime trainer Angelo Dundee. The party will feature a dinner, entertainment and speeches. She described it as a “retrospective look and celebration” of Ali's life. “It's significant for anyone to turn 70 years old,” Kahnke said. “But for such a global icon, who has literally touched the lives of millions of people, it's a momentous event to celebrate.”
