Dana White is not happy with Jason Aldean.

The UFC president said he invited the country music singer to perform the national anthem at UFC 216 on Saturday, where several first responders and survivors of last week's mass shooting would be in attendance.

White told TMZ that Aldean's people turned down the offer because he was too shaken up from the shooting and might never perform live again.

When White saw Aldean open Saturday Night Live, he felt he was lied to.

"His image was more important than coming back to Vegas and playing for the people who are his fans and who got shot watching him play," White said to TMZ. "F— you Jason Aldean. Stay out of Vegas."

White also said he reached out to several other country music stars, but they all turned him down.

"Those are people who buy your albums and none of you country music people could sing the anthem in front of survivors and 1st responders?" said White to TMZ.

White opened UFC 216 by honoring the victims and first responders of the tragedy.

White said the UFC will be donating $1 million to the families of victims and others affected by the shooting.

The UFC is also selling special Vegas Strong T-shirts on their website, with all proceeds going to charity.
