Timothée Chalamet and Kylie Jenner really are getting serious!

The lovebirds, who have been showing off their adorable PDA a lot lately, have reportedly moved in together! Wow!

According to The US Sun on Thursday night, sources (who also spoke to OK! Magazine) revealed in December that the Dune star has been “quietly moving things” into his girlfriend’s Los Angeles mansion — this just one year into their romance! An insider close to the couple dished:

“When he’s in LA, Timothée lives with Kylie. She’s so private that her sisters don’t even know about it yet.”

OMG! Her family doesn’t know?!? Why would she keep something as exciting as this from them?

Right now, it’s a bit unclear why she hasn’t been more open about this big step in her love life with her family — maybe she thinks her sisters would have a problem with the actor moving in already? Why else hide it?! The only clue we have so far is the fact that the 26-year-old has been very “protective” of her current relationship in general.

Not only have they kept a pretty low profile since linking up (though they have started to step out a bit more together — like at Sunday’s Golden Globes), but the Khy founder feels pressure to keep their connection safe from outside forces. A source told DailyMail.com earlier this week after all the drama with Selena Gomez:
“Kylie doesn’t feel threatened by her, but she is heavily protective over her relationship with Timothee. […] She loves him and isn’t going to let him go. She knows that women would love to break up what they have.”

Oof. It can’t be easy to be in a relationship when you’re constantly afraid others are going to try to mess with it! We guess that’s why she probably prefers to be much more private with it!

As for why they are taking this big step so quickly, it’s apparently so they can savor all their time together amid their super busy schedules, The US Sun‘s insider added:
“[The] idea of having the same home base — it’s the best way to see one another with their busy schedules. They miss each other so much when they’re apart, and that’s been most evident recently with his huge press tour.”

Timmy’s been all over the place promoting his new flick, Wonka, while The Kardashians star has been busy working on her various brands and, of course, raising her kiddos, Stormi, 5, and Aire, 1, both of whom she shares with ex Travis Scott. By the way, they are loving the new addition to their home! The source noted:

“They’re obsessed. All Kylie ever wanted was for someone to love her for her and to love the kids, and Timothée checks those boxes. She’s so happy to make things official and be living with him.”

Aw!!

This is so exciting for them! We hope her family approves!

Kylie Jenner Is Hiding Timothée Chalamet Romance From Her Children!

Kylie Jenner isn’t ready to introduce her boyfriend to her kids yet! Not as her boyfriend anyway!

A source for Us Weekly claimed the 26-year-old reality star’s two children, 5-year-old daughter Stormi Webster and 1-year-old son Aire Webster, have met Timothée Chalamet. However, their encounters have been very low-key! Timothée only interacted with her little ones in “group situations” with other family members and pals around them. And get this — Kylie has introduced him to Aire and Stormi as “one of mommy’s friends”! The insider explained:
“Timothée has met them in group situations where there were other family members or friends around. It hasn’t been anything where it’s just Kylie, Timothée and the kids in an intimate setting. And she introduced him as one of Mommy’s friends. Kylie feels like it’s [still] too soon to let them know anything about their relationship.”

That’s fair since she and the 28-year-old actor haven’t even reached the one-year mark in their relationship yet! Introducing kids to a new partner is both a huge step in a relationship and can be a tough transition for her family, so we get why Kylie is taking her time with the delicate process. But if he is “moving things” into her mansion in Los Angeles as reports previously claimed, does she plan on still calling him “mommy’s friend” to her little ones? Mommy’s pal who does sleepovers all the time?? LOLz! Or will he finally get the label of boyfriend for them? Hmm.

And how does her baby daddy and ex-boyfriend Travis Scott feel about Timothée eventually being in their kids’ lives? According to the same source, the former couple don’t discuss their love lives with each other! They strictly keep their conversations about the kids! But that doesn’t mean the 32-year-old rapper is 100 percent on board with Kylie’s relationship with Timothée! The source said that when the pair began dating last year, Travis threw some shade at their relationship! They revealed:

“When Kylie and Timothee first started dating, Travis made a comment in passing that he doesn’t see it lasting, but he hasn’t mentioned anything since.”

Yeesh! The insider continued:
“Travis is a great co-parent, and he doesn’t have a strong opinion on Kylie’s relationship. He’s dating a lot of women at the moment.”

Travis “doesn’t have a strong opinion” about it? The Goosebumps artist allegedly said they wouldn’t last! And mentioned him in a song! We would categorize that as a “strong opinion!”

Despite the comments, Kylie and Timothée appear to be getting “super serious.” They are even publicly saying the L-word now, as we all saw on national TV! So Travis may have to get used to seeing the Dune star around for a while!

Reactions, Perezcious readers? Sound OFF in the comments below.
