The pop star sent waves of worry through his fanbase when he was photographed in tears while on a bike ride on a busy road in New York with his fiancée Hailey Baldwin.
While some were rather cynically quick to suggest there may be trouble in paradise, others noticed that the singer seemed to be overcome with emotion as the pair took to a curb to hold each other and take a moment together by the side of the road.
The 'Sorry' singer has since quelled any gossip that stemmed from the emotional outburst, saying; “You got good days and you got bad days. It’s not real if it doesn’t have any bad days.”
When responding to questions about the tear-filled photos, newly-engaged Bieber held up his copy of the Christian marriage preparation book - full title The Meaning of Marriage: Facing the Complexities of Commitment with the Wisdom of God - which according to the book's description is a guide to “what marriage should be according to the Bible.”
Written by New York Presbyterian Church pastor Thomas and his wife of 37 years Kathy, it is "essential reading for anyone who wants to know God and love more deeply in this life," according to its description.
"This book shows everyone -Christians, skeptics, singles, long-time married couples, and those about to be engaged-the vision of what marriage should be according to the Bible."
Among the teachings in the book are: "no two people are compatible, change begins immediately"; "person becomes more ideal as you live together and submit", and; "a good marriage is more painfully hard to achieve that athletic or artistic prowess".
"You will have to make changes that you don’t want to make, and so will your spouse" Chapter One, The Secret of Marriage, reads.
"The journey may eventually take you into a strong, tender, joyful marriage. But it is not because you married the perfectly compatible person. That person doesn’t exist.”
Justin proposed to Hailey during a trip to the Bahamas last month, and later confirmed the news on Instagram in a sweet tribute post dedicated to the blond beauty.
He wrote: "Was gonna wait a while to say anything but word travels fast, listen plain and simple Hailey I am soooo in love with everything about you! So committed to spending my life getting to know every single part of you loving you patiently and kindLY.
"I promise to lead our family with honor and integrity letting Jesus through his Holy Spirit guide us in everything we do and every decision we make. My heart is COMPLETELY and FULLY YOURS and I will ALWAYS put you first! You are the love of my life Hailey Baldwin and I wouldn't want to spend it with anybody else. You make me so much better and we compliment eachother so well!! Can't wait for the best season of life yet!. (sic)"
