Kylie Jenner is reportedly drawing firm boundaries when it comes to her relationship with Timothee Chalamet, especially where her sisters are concerned. According to RadarOnline.com, the beauty mogul has become increasingly protective of her Oscar-nominated boyfriend and isn't thrilled about how much attention he's been getting from her famous siblings.

Despite the Dune star making efforts to blend into Kylie's world-spending time with her children and even bonding with family matriarch Kris Jenner-Kylie is said to be growing suspicious.

She's allegedly worried her sisters-particularly Kendall, Kim, and Khloe Kardashian, all of whom are currently single-could either manipulate her relationship or worse, steal the spotlight altogether.

"Kylie loves her sisters dearly, but she doesn't trust them further than she can throw them, especially now that Kendall, Kim and Khloe are all single," a source told RadarOnline.com.

Oscar party tension and family flirtation rumors

The tension reportedly reached a boiling point after the Vanity Fair Oscar Party, one of the few public outings where Kylie allowed her sisters to mingle freely with Chalamet. According to insiders, Kendall and Kim were "fawning all over him with their mouths hanging open."

"Kylie is convinced that if they were continually allowed to be in the presence of Timothee's bona fide charisma and charm, they'd melt, and she doesn't want that," the insider added.

The makeup mogul's paranoia may not be entirely unfounded if past family drama is anything to go by. The source pointed to earlier rumors involving Kim Kardashian and Travis Barker, now married to sister Kourtney Kardashian.

In his 2015 memoir, Barker itted to having had a "flirty relationship" with Kim back in the days when she was working as Paris Hilton's closet organizer. Although he insisted they never slept together, the flirtation was enough to stir up drama years later.

"So Kylie is keeping her eye on Kim, who's still a big flirt around Travis as far as she can tell," the source said, suggesting a pattern of behavior that's left Kylie on high alert.

Sources say Khloe has a habit of "telling embarrassing stories about her," and adds to the overall tension in the room.

"There's tension and competitiveness whenever Khloé's around because she is insecure about her looks and needs affirmation that she's hot and sexy," the insider revealed.

Kendall, meanwhile, is reportedly seen by Kylie as another threat-not due to flirtation, but her habit of physical affection.

"Kendall is just as bad as she likes to hug and embrace everybody in the room, including her sisters' boyfriends, and Kylie will have none of that happening around Timothee," the source added.
