Remember earlier this week when Nick Cannon claimed Mariah Carey doesn't know Kim Kardashian? Like who Kim is? Yeah, it turns out that's total BS.
As a human being who lives in the world and presumably has Internet access, Mariah is fully aware of who Kim is. In fact, not only does she know Kim's name, the two women have met on at least one occasion:
When Jimmy Fallon took over as host of The Tonight Show, he kicked off his first episode with a sketch in which various celebrities walked onstage to give him money.
Two stars who waited in line together before their cameo were - you guessed it - Kim and Mariah.
Now, since Mariah is Nick Cannon's wife and Mariah his long-ago ex, they probably didn't do much talking, but the fact remains, they definitely know each other.
