Kim Kardashian is reportedly not happy with her younger sister Kendall Jenner’s suggestion about her blossoming romance with Lewis Hamilton.

According to Star Magazine, the 45-year-old reality TV star is disappointed with how her 30-year-old sister reacted to her relationship with the F1 star.

An insider told the publication that Jenner has advised Kardashian to “take things slow,” as she has known Hamilton for a really long time prior to their romance.

The Vogue supermodel and the Ferrari star “have been party pals for years, and she knows a lot of the dirt on him,” the source dished.

They added, “That’s why she feels like it’s her duty to warn Kim to keep her feelings in check. She’s not telling Kim to drop Lewis; she just wants her to take things slow.”

However, Jenner’s take on their relationship wasn't met with open arms by Kardashian, who even accused her sister of being “jealous” of her romance with Hamilton.

“Kim says she’s a grown woman who doesn’t need her permanently single sibling trying to ruin her fun,” the tipster noted.

The confidant further revealed that “Kim says she doesn’t need her little sister acting like some relationship expert who knows men better than she does.”

“She’s very offended that Kendall thinks she can’t handle herself with Lewis,” they concluded.

Kim Kardashian and Lewis Hamilton hard-launched their relationship at Super Bowl LX in 2026.
