Cardi B’s best moments co-hosting 'The Tonight Show'

Rap superstar Cardi B joins The Tonight Show starring Jimmy Fallon not just as a performer, but as co-host. The “Money Bag” singer quickly picked up the finer points of hosting. She did bits with Fallon during the monologue, and most importantly for any host, she engaged the guest, John Mulaney.

She also engaged with fans. One lucky fan who happened to be wearing a Cardi B sweatshirt was brought onstage and she left an outgoing voice message on his phone, though she forgot to ask for a name and number of whomever may be calling.

Cardi also finally explained the meanings behind some of her signature sounds. There’s, as they spelled it, “Eeeeooowwww,” which is, “…like a sad cat sound. Like a cat that’s going through pain.” Then there’s “Eeeeooowwww! (higher),” which as she put it, “It’s like, ‘Oh my god, I’m hosting the Jimmy Fallon show. Eeeeooowwww!’” And of course there’s “Okuuuuuuurt,” which is”…like a cold pigeon in New York City.”

Before closing the show with a performance, Cardi and Fallon played a game of Box of Lies. Fallon asked Cardi, “What is in your box?” Cardi answered, “Not a penis.” Cardi was definitely not lying about that.
