The 26-year-old rapper opened the post saying she was doing the video "justlbby-style" by only filming one hand and then thanked her fans for the nominations, saying she feels like "I'm that bitch right now."
"I remember when all I ever wanted to do was chart on the Hot 100 charts," Cardi B said in the video. "I was like, if I chart, I'm official. Like I celebrated my first charting — when I charted at No.] 75 — the same way I celebrated my first No. 1 on the Billboard charts."
The rapper leads all nominations; she's nominated 21 times across 18 categories and will compete against herself in three: top Hot 100 song, top selling song and top collaboration. The 2019 Billboard Music Awards will take place at the MGM Garden Arena in Las Vegas on May 1.
