Kylie Jenner and Timothée Chalamet have been dating for two-ish years, just went red carpet official, and appear to be living together. And if you're wondering what the next step in their relationship is...it could be pretty major.

A source tells Entertainment Tonight (via Buzzfeed) that "Kylie is so in love" and that "When they’re not physically together, they’re constantly texting. She loves learning about his world and supporting him. It’s been nice for her to expand her usual scene and experience a relationship with someone very different than who she’s dated in the past."

Meanwhile, the insider says Timothée is "so great" with Kylie's kids, and that Kylie has "told her closest friends that she would love to have another baby with him someday."

This comes amid a source telling Us Weekly re their recent red carpet appearance that "Kylie’s really happy and relieved they finally made their debut. It was time and she wanted to publicly support him and show how proud of him she is. She and Timothée have gotten really serious, and this was a big step."

"Everything is going really well," they added. "She’s proud to stand by him and felt like it was the right time to share that part of their relationship. They are in a really good place. He makes her feel calm and confident and it is a different relationship from what she has had in the past. They are practically living together at this point, as he stays at her house often when he is not working. He has been fully integrated into her life."
