VIDEO : Mariah Carey's Legendary Jennifer Lopez Shade Was Her 'Trying To Be Nice'

It was so shady that it's now one of the most popular memes and gifs of all times.

Years ago, Mariah Carey was asked during an interview about fellow singer/actress Jennifer Lopez. Carey shook her head and proclaimed, "I don't know her." It became so famous that even Carey got in on the joke, years later holding a paddle with the phrase.

Jennifer Lopez has been quoted as saying the pair do know each other.
