There was plenty of star power at Celebrity Fight Night in Phoenix. Saturday night's event was one of the biggest charity events in the country.
The stars walked to red carpet at the JW Marriott Desert Ridge Resort and Spa.
The annual event honors Muhammad Ali. In its 18 years, more than $80 million has been raised. Most of it goes to the Muhammad Ali Parkinson's Center.
"You got to support the champ. Support the champ, support people who go through this horrific disease, what they do for one night, it's unbelievable," says Kevin Sorbo.
