Reba McEntire is such a hot ticket that three fans bid nearly $1 million to have lunch with her! The worthy cause was the Celebrity Fight Night auction in Phoenix, Ariz., this past weekend, benefiting the Muhammad Ali Parkinson Center in Phoenix.

According to Showbiz 411, the $900,000 bid was made by Bill Austin of the Starkey Hearing Foundation, Bob Parsons of GoDaddy and philanthropist Walter Scott.

Celebrity Fight Night was founded by the legendary boxer to raise money for Parkinson's disease research. The event, emceed by Reba for the fifth time, brought out an array of musicians, singers, athletes and comedians who helped raised a total of $5 million for the charity.

Many of proceeds were raised through the auction, which apparently was a feast for music fans. One bid for $70,000 entitles the winner to hear the original 'Soul Man' Sam Moore sing his hit while accompanied by Randy Jackson on bass and comedian Chris Tucker singing and goofing around.

Kris Kristofferson, Waylon Jennings' widow Jessi Colter, Eagles front man Glenn Frey, John Corbett and his band, with his beau, Bo Derek, baseball great Dave Winfield and many others participated in the event.

In addition to one-of-a-kind auction items, the guests shared memories with the crowd, including Glenn, who told the audience. "Back in 1970, Don Henley, Jackson Browne, J.D. Souther and I hit on every waitress at the Troubadour (the Hollywood night club). But they were only interested in one guy: Kris Kristofferson."

Reba was persuaded to accompany Kris onstage to perform his iconic 'Me and Bobby McGee.'

Asked later if she knew the song, Reba responded, "Are you kidding? I've known it all my life. But they didn't even tell me I'd be singing. Oh my!"

Another musical highlight was a song for Ali performed by Kris and Jessi, which Jessi introduced by saying of her late husband, "Waylon wrote the song but he never got to perform it for anyone except the Champ."
