Timothée Chalamet and Kylie Jenner have taken the next step in their three-year relationship. "Kylie has never dated someone like him and it's been refreshing because they have a very easy chill relationship. They basically live together at this point," a source exclusively tells Us Weekly. "Kylie will stay at his house when she doesn't have the kids, or when she wants to be in the city, and he spends a lot of time at her house in Hidden Hills." Chalamet, 30, and Jenner, 28, have been together since 2023 - the Kardashians star's first relationship since breaking up with rapper Travis Scott.
