Kaia Gerber and Lewis Pullman are "so in love".
The 24-year-old model and Lewis, 33, have built a strong foundation for their burgeoning romance.
A source told People: "Kaia and Lewis are the real deal and so in love."
The loved-up duo - who were first linked in early 2025 - are both children of well-known stars.
Kaia is the daughter of model Cindy Crawford and businessman Rande Gerber, while Lewis is the son of actor Bill Pullman and dancer Tamara Hurwitz.
The insider explained: "Cindy and Rande love them together and they feel he’s a part of the family already.
"They feel as though they’ve been together for a lifetime. Lewis is so kind and gentle towards Kaia, he gets along with all her friends and is so loving."
Earlier this year, a source claimed that their relationship "felt very genuine right away".
Speaking about their burgeoning romance, the insider told People: "It just felt like they were naturally part of each other’s lives pretty quickly. They’ve kept things very low-key.
"You don’t see them trying to be out everywhere. It’s more about spending time together, often with their families. They both seem very down-to-earth. It’s very family first."
Meanwhile, Kaia - who has previously dated the likes of Pete Davidson, Jacob Elordi, and Austin Butler - has pushed back against the idea that she's a romantic.
The brunette beauty - who is one of the world's highest-paid models - told Harper's Bazaar magazine: "I would say I romanticize.
"I don’t know if I’m romantic. I’m a daydreamer. I play out every scenario in my head. I can kind of convince myself that someone is anything that I want, even if they do everything to prove that they’re not."
Kaia admits that there are positives and negatives to her vivid imagination.
The runway star - who won the Model of the Year gong at the British Fashion Awards in 2018 - said: "My imagination is really strong, and it’s been such a gift in my work. Not always a gift in relationships."
