Country music star Jason Aldean paid tribute to the Las Vegas shooting victims on "Saturday Night Live," something UFC president Dana White is not happy about. Just days after Aldean appeared at the Route 91 country music festival, TMZ reports that White invited Jason to sing the national anthem at UFC, an event that numerous shooting survivors and first responders were invited to.

White claims Aldean turned the gig down because he was still reeling from the mass shooting that took place when he was on stage at the Route 91 festival. Now he's lashing out at singer because he took the "SNL" gig instead.

Why did Jason Aldean turn down the Vegas gig?

According to Rolling Stone, Jason appeared on "Saturday Night Live" just one week after he performed at the Route 91 country music festival. It's not clear if Aldean was already scheduled to appear on "SNL" or if it was a last-minute gig, but there was plenty of positive feedback for his opening speech, followed by his cover of the late Tom Petty's "I Won't Back Down."

Despite the applause, Aldean received on "Saturday Night Live," UFC's Dana White told TMZ the country music star's "people turned down the offer." They reportedly told White that Jason was "shaken up" from the Las Vegas shooting and there was a possibility that he would never perform live again.

The UFC event was scheduled to take place at the same time Jason flew to New York City to make his "SNL" appearance. White states that the singer's image was "more important than coming back to Vegas" to play for the very fans who "got shot watching him play" at the Route 91 festival.

Vegas survivors and first responders attend UFC 216

Aldean wasn't the only country music star who turned down an invite to UFC 16. However, the show went on. According to TMZ, 15 survivors and hundreds of first responders who attended got to see a performance by rapper, Everlast.

It's been a tough week for those who survived the mass shooting and the friends and families of the 58 victims.

On October 1, Jason Aldean was in the middle of his set at the Route 91 country music festival when Stephen Paddock opened fire on the crowd of approximately 22,000 people.

According to CNN, Paddock broke two windows in his hotel room at the Mandalay Bay Resort and Casino last Saturday night. He then opened fire on the outdoor festival, killing 58 people and wounding close to 500. Paddock reportedly committed suicide before police entered his room.
