Even though Cardi B has a strong chance of winning her first Grammy, she is feeling nervous heading into Sunday’s show.

The rapper said she’s been filled with anxiety about the potential of winning an award and executing her performance at the 61st annual Grammy Awards. She said she is trying to stay on an even keel, preparing for the “best of the worst.”

“You can never really be so sure,” she said while promoting her new Pepsi “Okurrr” commercial, which will air during the awards telecast on CBS. “For some reason ... my mind has been like anxiety, anxiety.”

Cardi B is nominated for five Grammys, competing for album and record of the year. She also received nods for best pop duo/group performance, rap performance and rap album.

Before the awards last year, she had high hopes. She was a former stripper who became a social media darling and reality star before she turned into a pop culture sensation and earned two Grammy nominations. She walked away empty-handed, but she used the letdown as motivation.

“A lot of people were like, ‘You’re going to win,’ but then I didn’t,” she said. “I was like, ‘I just got to work harder to get one.’ ”

The “Okurrr” commercial — a follow-up to the “More Than OK” Super Bowl ad featuring Steve Carell and Lil Jon — is validation for Cardi B.

“Sometimes I ask myself, ‘Like, am I enough? Am I there yet?’ ” she said. “But when you do these types of commercials, it is like they certify you to the world and to yourself.”
