They're looking to put down roots.

We caught Hailey Baldwin house hunting with her realtor yesterday in LA, and it looks like the model and husband Justin Bieber are eager to find a place to call home. As if this wasn't a big enough task, they're also in the middle of planning their formal wedding ceremony, so to say they're checking a lot of things off their list would be an understatement.

"They are still in the middle of deciding whether or not they want a big or small wedding. They would love a small wedding, but they have so many people that they want there and they know once they start planning, it could become bigger," a source dished to Us Weekly.

"Right now, they are focusing on looking for a new house in L.A. They’re looking at houses in Brentwood, Bel Air and Beverly Hills. They’re renting now but want to buy something big enough for a family. They want kids — soon," the source added.

The Biebs has struggled with his emotions in recent months, but their relationship has been a grounding force in his life.

"Hailey is so happy and Justin is doing great. He’s obviously still trying to focus on his mental health and staying in a good space, and that’s their main priority right now. They’re both super family-oriented and are excited about the next chapter of their lives together. Hailey can’t wait to be a mom," the insider revealed.

We're starting to think this marriage is the real deal!
