They're taking this commitment seriously.

Justin Bieber and Hailey Baldwin dropped by their pastor's house yesterday afternoon, and the couple has been taking their premarital counseling very seriously ever since they got engaged. The pair don't plan on tying the knot until 2019, but they want to make sure they're good and ready when they finally walk down the aisle.

A lot of people were shocked when The Biebs popped the question to the model after just a couple months of on-again dating, and one of those people was his ex Selena Gomez, but the "Come & Get" songstress has reportedly never been happier after closing the door on their romance.

"Selena’s on-again, off-again relationship with Justin left her a nervous wreck. Now that she’s accepted that it’s over for good, she actually feels relieved to close that chapter of her life. For the first time in years, she feels free," a source dished to Life & Style.

"She’s distanced herself from her old Hollywood life and the fake friends that came with it. She only surrounds herself with genuine people who love her for who she is. Selena has grown up a lot and feels so much more comfortable in her own skin," the source added.

Hailey probably wants to make sure JB's feelings for Selena are truly gone before she becomes Mrs. Bieber!
