Is Shane Bieber Related to Justin Bieber? The Baseball–Pop Star Connection Explained

As Toronto Blue Jays ace Shane Bieber prepares for Game 4 of the World Series against the Los Angeles Dodgers, a familiar question is trending again: Is Shane Bieber related to Justin Bieber? The answer is simple — no, they are not related by blood or marriage. The two just happen to share one of the world’s most recognizable surnames.

The coincidence has led to years of jokes, viral moments, and even friendly interactions between the baseball star and the pop icon. Both have embraced the confusion with humor, turning a simple mix-up into a lighthearted part of sports and pop culture crossover history.

Shane Bieber and Justin Bieber: Same Name, No Family Ties

Shane Bieber, the 2020 American League Cy Young Award winner, grew up in Laguna Hills, California. Justin Bieber, the global pop phenomenon behind hits like “Peaches” and “Sorry,” hails from Ontario, Canada. Despite sharing the same last name, they have no known familial connection or common ancestry.

Back in 2018, Shane leaned into the running joke during Major League Baseball’s Player’s Weekend, wearing a jersey labeled “Not Justin.” The tongue-in-cheek move quickly went viral, catching the attention of Justin himself. Soon after, the singer responded with a playful nod — posting a photo in a custom jersey that read “Not Shane Bieber.”

“A lot of people like to make the joke and mistake me for him,” Shane told reporters that year. “So I figured I’d make it obvious and play along.” Since then, fans have dubbed it the “Bieber vs. Bieber” gag — a harmless and fun mix-up that continues to resurface whenever Shane takes the mound on a big stage.

Viral Moments and the 2025 World Series Spotlight

Fast-forward to 2025, and the connection still gets fans talking. During Game 3 of the World Series at Dodger Stadium, Justin Bieber was spotted in the crowd wearing a Blue Jays jersey with Shane’s number 57. The sighting sent social media buzzing, especially after Shane’s wife, Kara Bieber, shared clips of the pop star cheering from the stands.

Shane, one of Toronto’s top pitchers this postseason, is expected to play a crucial role in Game 4 as the Blue Jays look to even the series at 2–2. While the two Biebers may not share family ties, they do share a name that unites two massive fan bases — baseball and pop music — every time the World Series spotlight hits.

A Lighthearted Pop Culture Crossover

The “Bieber connection” has evolved from a simple case of mistaken identity to an enduring inside joke. It shows how humor and sports culture intersect with entertainment, especially in an era where viral moments spread faster than ever. Even years later, fans still bring up the jersey exchange as one of the most iconic baseball memes of the late 2010s.

So, while a “Bieber Brothers World Tour” might sound like a dream for fans of both baseball and pop music, it remains purely a play on names — not a family reunion. The two Biebers continue to shine in their respective fields, proving that sometimes, sharing a name is enough to create an unlikely pop culture bond.

In short: Shane Bieber and Justin Bieber are not related. But their shared name has sparked one of sports’ most entertaining and enduring mix-ups — one that keeps fans smiling every baseball season.
