Despite rumors that they’re “just having fun,” all signs are pointing to Gigi Hadid and Bachelorette alum Tyler Cameron getting pretty serious. First, her sister Bella Hadid followed him on Instagram, then he showed up at her grandmother’s funeral in the Netherlands and now, Gigi is helping Tyler look for apartments near hers in NYC.

And they talk all day long, a source tells E!: "Tyler has been looking at apartments that are in the same area as Gigi's in NYC. She suggested a few to him and he wants to be nearby. They are getting pretty serious and it's not slowing down. They text all day every day and see each other multiple times a week."

An insider tells E! that despite their original intentions, things are developing: "Neither of them really anticipated that it would turn in to what it has. For Tyler, it's still pretty casual, but they are spending a lot of time together and really like each other. Gigi asked him to come to the Netherlands and he agreed. He's a very supportive person and someone that's great to have around when you're going through something. He's rock solid and very kind. They didn't put too much thought into it. They are together a lot and she didn't want to go without him."

The source adds, "They aren't talking about the future or what any of this could become, they are just going with it. But he loves being with her and they are really clicking."

Bottom line: neither one is dating anyone else.
