Kim Kardashian is not crossing her sister Kourtney anytime soon. In a newly released segment from her Jimmy Kimmel Live appearance in July, the 38-year-old mother of three plays a game of “3 Ridiculous Questions” with Jimmy.

When asked which of her sisters is most likely to sue her, Kim responds: “Kourtney. She is ruthless.”

Kim says she jokingly told her she’d sue her “when I used her character in a video game. And I paid her. But yeah — she wanted more.”

This is just the latest snark directed at Kourtney courtesy of Kim. Four months ago on Keeping Up With the Kardashians, she infamously dubbed Kourtney the “least exciting” sister “to look at.”

On last week’s she attempted to make it better by calling her just the “most boring.”
