The rodeo says 75,580 people were in attendance to see the rapper perform Friday night. That beats Garth's record of 75,577 people, set on March 18, 2017.
"She doesn't hold back anything and I think that if you've never experienced a Cardi B moment, the reality of it is that you'll either love it or you'll be like, 'This is too much!'" fan Jenny Sanchez laughed. "For me, it's like it's not enough, I'm always ready for it."
Cardi didn't end her show at the rodeo Friday night, the rapper also appeared at Spire Nightclub, where she was spotted dancing and interacting with fans.
