Kylie Jenner Reportedly Sets Boundaries Over Timothée Chalamet Amid Trust Issues With Sisters

Kylie Jenner is reportedly laying down the law when it comes to her romance with actor Timothée Chalamet. According to recent reports, the beauty mogul and reality TV star has become increasingly protective of her relationship — especially around her famous siblings.

Sources close to the Kardashian-Jenner family say Kylie is feeling uneasy about how much time Chalamet has been spending with her sisters — all of whom are currently single. With Kendall Jenner, Kim Kardashian, and Khloé Kardashian back on the dating scene, Kylie is allegedly making it clear that her boyfriend is off-limits.

Kylie Jenner Concerned Over Sisters’ Behavior Around Timothée

While Kylie is known to be close with her sisters, insiders suggest she has lingering concerns about how their flirtatious behavior might affect her two-year relationship with the Dune actor. One report claims she wasn’t thrilled after observing how Kim and Kendall acted around Timothée during a high-profile afterparty.

“Kylie adores her sisters, but she’s not blind to their dating patterns — especially now that they’re all single again,” said a source familiar with the family dynamics.

The insider also shared that Kylie feels Chalamet’s natural charm could unintentionally attract the attention of her siblings. Past instances — like Kim’s alleged flirting with Kourtney Kardashian’s husband, Travis Barker — have only heightened her concern.

Trust Issues Reportedly Center Around Kim Kardashian

Among the sisters, Kim is reportedly the one Kylie is most worried about. Due to Kim’s flirtatious nature and past behavior, Kylie is said to be extra cautious when the two are in the same room as Timothée.

“She’s not taking any chances,” the insider added. “Kylie’s just being careful. She knows how easily boundaries can be crossed in this family.”

While no official comments have been made by Kylie or her sisters, fans are keeping a close eye on this evolving family dynamic. If true, this drama could be another plotline for an upcoming season of The Kardashians.
