WIZ KHALIFA smoked what appeared to be a huge blunt on stage ahead of the Mike Tyson and Roy Jones Jr’s fight.
But fans were not too overwhelmed with the live performances by the artist and French Montana.
With an undercard full of fights, viewers who purchased the pay-per-view wanted to see more action and less rapping.
One said: “I thought I ordered a fight not a concert.”
Another said: “I didn’t tune into the Tyson fight to watch Wiz Khalifa perform his greatest hits.”
One added: “I clicked the link to watch the Mike Tyson fight and a Wiz Khalifa concert was going on???”
Another added: “I thought this was a Tyson fight. I don’t want to watch a Wiz Khalifa concert. No offense Wiz.”
One tweeted: “Pretty upset I paid $50 to watch mike Tyson fight and instead I’m watching French Montana perform.”
