We all remember that tragic ad. It happened many months ago, but because of Kendall's stone cold silence, it's stayed in the forefront of most people's minds.
It was incredibly tone-deaf and offensive, mainly because it recreated this image of a Black Lives Matter protest, and made out that a single Pepsi (from a privileged Caucasian girl who has never spoken out against the issue) would end police brutality.
Even Martin Luther King Jr.'s daughter Bernice King sassed Kendall.
Last month, Kim Kardashian tried to explain why Kendall had never apologised, but that also fell flat because her excuse was that she never wanted anybody to see her cry.
So, now, after Kendall completely ignored the fact that it ever happened, she has mentioned it in passing during a Keeping Up With The Kardashians trailer.
"I feel like my life is over," she says to Kim, who replies, "You made a mistake!"
Annnnnd that's it! We guess we're going to have to wait for the actual episode to air to find out if an apology follows, but 'til then, fans are still annoyed.
