Last Saturday, Rascal Flatts were among the performers at Muhammad Ali's Celebrity Fight Night in Phoenix, Ariz. Tom Hanks was also there, rubbing elbows with the other celebs at the gala, which Reba McEntire hosted. Who knew the former boxing champ was such a big fan of county music?

Rita Wilson, Miley Cyrus, Lionel Richie and John Corbett were also on hand at the star-studded event. Over $9 million was raised for Parkinson’s disease research and for the Ali Center. This weekend, the trio will be performing their hit song 'Banjo' with comedian Steve Martin at the 47th annual ACM Awards in Las Vegas.
