Hailey and Justin Bieber welcomed their son, Jack Blues Bieber, into their lives in August 2024, and they couldn't be happier. “Jack’s brought them closer together,” said a source, “but new parenthood is hard on all couples.

The source notes that it's "quite sad that there are constant split rumors" about Justin and Hailey, and says that "Anyone who spends a lot of time with them can tell how in love they are and also how super focused they are on their marriage.
