"Oh lord, I'm not ready for this, my heart pumpin' fast," Cardi joked.
Cardi B may be a Grammy-winning artist, but even she gets nervous around celebrities.
In an interview with Access for her upcoming movie "Hustlers," the "Bodak Yellow" rapper, who is a former stripper, admitted she got a little anxious when she was tasked with giving co-star Jennifer Lopez a lap dance.
"I was really nervous, to be honest with you," Cardi said. "Oh god, I got to sit with J.Lo...this is crazy. Oh lord, I'm not ready for this, my heart pumpin' fast. Like oh my god, I got to rub my vagina on them because that's how you really give a real lap dance if you really trying to get them dollars."
"That's how you work the clock," she added.
When asked if there was a bonding moment while filming, Lopez shared a funny anecdote about Wu where she thought she had broken the actress' nose.
According to the ladies, during a scene in the film, Lopez's character grabs the phone from Wu's character and they have a little fight. Instead of fully faking the mini brawl, Lopez and Wu really went for it.
"[Wu] started fighting more than me even and the phone smacks her in the nose and cuts her nose open," Lopez recalled to Access, adding that Wu was "bleeding." The "Fresh Off the Boat" star shook the whole thing off though, despite getting a "big, big bump" on her nose.
"I got so nervous! I was like, 'I broke her nose!" Lopez added. "And she was like, 'It's totally fine.'"
"She was such a trooper," Lopez concluded of Wu. "I feel like we bonded in that moment."
"Hustlers" hits theaters September 13.
