Carrie Underwood, Muhammad Ali and Gronk all in the same place???
Hell yeah -- and it was awesome!!!
The superstars all came out to Phoenix, AZ this weekend for Celebrity Fight Night -- a massive fundraising event hosted by Reba McEntire.
Tons of stars helped raise money for tons of worthy organizations including the Muhammad Ali Parkinson Center, Phoenix Children's Hospital and Barrow Neurological Foundation.
The celeb guest list was massive -- with Kurt Warner, David Foster, RFK Jr., Brooks & Dunn among the stars.
One of the highlights ... when Gronk got onstage and busted out some dance moves. Also a funny moment when he botched the lyrics to "Ice Ice Baby."
Maybe next year, Gronk.
