“Like, I am so sick and I don’t understand why because when I was in New York I was going out in sweaters, toes out, everything. I was good.

“Soon as I landed in Miami bro… I’ve been telling people I am allergic to Miami. I’m allergic to Florida. I’m allergic to this state. Like I’m allergic to this state.

“It doesn’t even make no sense. Like, as soon as I landed four hours later, I felt a little cough, my chest started getting tight.

“Well, I’ve been fighting for three days and I have a huge performance later. Huge performance, like I get that it’s New Year’s but I have this huge performance. And I’m fighting, fighting.”

The musician was joined on the bill for the US celebration of the new year by rapper Megan Thee Stallion, who performed in New York.
