Explained a source, “They bought a house and are trying to enjoy being newlyweds without the pressure of planning a big wedding. They want to do it at some point, but it’s not the focus right now.”In a recent interview with Vogue Australia, Hailey remarked, “Look, marriage is always going to be hard and I think good relationships are the relationships that you put the work into… I had never lived with someone before. I never had to cohabit with somebody in that way, so I was learning how to share space with someone for the first time. We were trying to bend in each other’s direction and learn what was comfortable.”News of Hailey and Justin’s sudden engagement broke in July 2018 while the couple was vacationing in the Bahamas.The “Love Yourself” performer popped the question with an estimated $500,000 engagement ring, which an insider confirmed to E! News at the time took his bride by surprise. “Her face was in shock but you could tell they are both so in love,” an eyewitness told us of the unforgettable moment.“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,” Justin wrote on Instagram when first confirming his engagement. “You make me so much better and we complement each other so well!! Can’t wait for the best season of life yet!”Hailey added, “Not sure what I did in life to deserve such happiness but I am so utterly grateful to God for giving me such an incredible person to share my life with!”It was more than three years ago that the newly minted husband and wife first sparked romance rumours. Following Bieber’s most recent split from on-again, off-again girlfriend Selena Gomez, the two rekindled their relationship in June of last year.“Ever since they reunited, they have been inseparable and Justin knows he can’t live without Hailey,” another source explained. “Justin and Hailey had talked about marriage before but Hailey didn’t think it would happen so quickly.” Congratulations to the happy couple! People was the first to report.
