Kylie Jenner Keeping Tabs on Timothee Chalamet Amid Split Rumors: ‘Totally Hung Up On Him’ (Exclusive)

Kylie Jenner is taking extreme measures to find out what boyfriend Timothée Chalemet is up to when her back is turned, Globe has learned, amid reports that the couple’s relationship is hanging by a thread.

With the Academy Awards fast approaching, “Timmy’s in full-blown Oscars promo mode right now,” a source says of the Marty Supreme star, 29, who lost Best Actor to Adrien Brody last year. “He’s got very little time for Kylie and is blowing her off a lot when she asks to hang out.”

Absence doesn’t always make the heart grow fonder, though — in Jenner’s case, it only fuels suspicion.

“Kylie’s trying to play things cool and insists it’s not over yet, but deep down, she knows it’s not looking good,” the source continues. “Her biggest worry is that Timmy will fall for someone else while they’re spending so much time apart. Women are throwing themselves at him all the time, she knows that, and it’s eating away at her insecurities.”

The breakup rumors certainly aren’t helping matters.

“Kylie wants so badly to confront Timmy and give him an ultimatum but dreads looking too desperate,” adds the source. “So, instead of blowing up his phone, she’s taking other measures to find out where he’s at and what he’s up to.”

However, it seems her famous family is done keeping up with him.

“They’re totally down on Timmy after he refused the invite to Kris Jenner’s 70th birthday party and they want Kylie to wake up and smell the coffee,” says the source. “But she’s still totally hung up on him and can’t let it go.
