Hailey Baldwin has long been in love with Justin Bieber — and now she’s gotten her happily ever after.

“Marrying Justin is Hailey’s dream come true,” a source close to the couple — who dated briefly in late 2015 and early 2016 — tells PEOPLE exclusively. “She always had a crush on him and she was so happy and excited when they got a bit older and dated.”

But after they split in 2016, Hailey, 22, was left heartbroken. “He wasn’t in the right place to be in a healthy relationship with anyone, and she was really upset with him,” says the source. “They both went their separate ways.”
