Kris Jenner keeps it very professional.

While introducing Culture Club at the first-ever iHeart80s Party in New York City over the weekend, the Keeping Up With the Kardashians "momager" experienced some audience boos during her introduction of the band's lead singer, Boy George.

An eyewitness from the event told ET, “It was nuts. I have no idea why, but people booed her the entire time she was trying to talk."

"We were in the 100 level and you couldn't hear her intro, just the boo's of the audience," the eyewitness added.
