Justin Bieber, Hailey Bieber, and Selena Gomez: The Full Relationship Timeline

In the article that follows, I trace a couple's timeline that spans more than a decade, an on-and-off relationship, and a rebuilding phase that led to marriage. If you'd rather look at a relationship you're in right now, ScanMyLove reads the conversations you're already having for the same kind of pattern. And if long-term patterns like these speak to your own history, I've designed an attachment style test that helps identify how you tend to bond in relationships. I've also written a book on the topic, Understanding Your Attachment Style, if you'd like to go further.

On January 1, 2026, Hailey Bieber posted a photo of herself and Justin Bieber kissing, captioned simply: "10 New Years together and counting." The caption marks a decade since the earliest documented overlap between the two — a decade that also contains one of pop culture's most closely followed on-and-off relationships, between Justin Bieber and Selena Gomez. Sorting out what actually happened, and when, means separating three distinct periods: the long Bieber-Gomez relationship, a brief and publicly acknowledged overlap in 2015, and the reunion with Hailey Baldwin that led to marriage and, eventually, a family.

The On-and-Off Years: Justin Bieber and Selena Gomez (2010–2018)

Justin Bieber and Selena Gomez's relationship began in 2010, when both were teenagers navigating early fame, and continued in an intermittent pattern for roughly eight years. Entertainment outlets including IMDb, Koimoi, and FlyFM have documented multiple public breakups and reconciliations across that span rather than a single continuous relationship. The two reunited again in 2017 before separating for good in March 2018.

Relationships that break up and reunite repeatedly are a documented pattern, not a rare exception — one analysis of the psychology behind reunited couples notes that a majority of adults report having experienced at least one on-and-off relationship at some point. The Bieber-Gomez years fit that broader pattern: years of public attention followed each reunion and each breakup, long before either the 2015 overlap or the 2018 split that would follow.

Selena Gomez in This Timeline

Selena Gomez appears in this timeline strictly for the dates that are part of the documented record: together with Bieber from 2010, reuniting in 2017, and separating in March 2018. Her life and relationships beyond this shared chronology, including her later engagement to Benny Blanco, are noted here only as dated facts, without further comment.

December 2015: A Non-Exclusive Overlap with Hailey Baldwin

During one of the pauses in the Bieber-Gomez relationship, in December 2015, Justin Bieber and Hailey Baldwin were seen together publicly, including a widely reported kiss around New Year's Eve. Both later confirmed, in public statements, that this period was not exclusive. That is the extent of what is documented and confirmed by both parties, and it is the only characterization this article uses for that overlap. In 2017, Bieber and Gomez resumed their relationship, which continued until it ended for good in March 2018.

2018: Reunion, Engagement, and Marriage

By June 2018, three months after the end of his relationship with Gomez, Justin Bieber and Hailey Baldwin were together again. This second chapter moved quickly by any measure.

From a Bahamas Proposal to a New York Wedding

Bieber proposed to Baldwin in the Bahamas in July 2018, roughly a month after their reunion. The couple married in a civil ceremony in New York in September 2018. Hailey Baldwin became Hailey Bieber, and the marriage has continued since, through the years that followed.

A fast transition from reunion to marriage is often framed, in relationship research, in terms of how couples build lasting commitment after periods of instability — a question explored in more general terms in work on earned secure attachment, which looks at how people build stability in relationships even after a difficult or uncertain history. Whether or how that framework applies to any specific couple is not something the public record can settle; what is documented is the sequence of dates itself.

Parenthood and a Decade of New Year's Together

In August 2024, Justin and Hailey Bieber welcomed their first child together. No further detail about the child is part of the public record referenced for this article, and none is added here.

Then, on January 1, 2026, Hailey Bieber shared the anniversary post that opened this timeline. The caption, in full: "10 New Years together and counting." Read against the fuller chronology — the 2015 overlap, the 2017–2018 period with Selena Gomez, the 2018 reunion and wedding, and the 2024 birth of their child — the post marks ten years since the first documented point of contact between Justin Bieber and Hailey Bieber, spanning a period that also included one of the most publicly followed on-and-off relationships of the 2010s.

Why This Timeline Still Gets Attention

Public interest in the Bieber-Gomez-Baldwin chronology has not faded with time. Part of that is simple arithmetic: a relationship spanning three names, eight years, one confirmed overlap, and one wedding produces more datable moments than most celebrity relationships generate, and each new development — an anniversary post, an interview mention, a magazine retrospective — tends to reactivate the full sequence rather than stand on its own. The January 2026 caption is one example: on its own, it is nine words under a photo. Set against the dates above, it becomes a marker of ten years since the earliest documented point of contact between Justin Bieber and Hailey Bieber — a decade that also happens to contain one of the more closely followed on-and-off relationships of the 2010s. I go further into how repeated on-and-off cycles can entrench a traumatic bond between two people in my book Trauma Bonding.
