As Toronto Blue Jays ace Shane Bieber prepares to take the mound for Game 4 of the 2025 World Series against the Los Angeles Dodgers, a familiar question is once again trending: Is Shane Bieber related to Justin Bieber? The answer, confirmed repeatedly over the years, remains a simple “no.” Despite sharing the same last name, Shane and Justin Bieber are not related by blood or marriage. Yet, the coincidence has fueled years of humorous viral exchanges between the baseball star and the Canadian pop icon.
The “Bieber vs. Bieber” Story
Who: Shane Bieber, Toronto Blue Jays pitcher and 2020 AL Cy Young Award winner.
What: Addressing renewed fan curiosity about his relation to pop singer Justin Bieber.
When: Ahead of Game 4 of the 2025 World Series.
Where: Dodger Stadium, Los Angeles.
Why: Justin Bieber was spotted in the crowd wearing Shane’s Blue Jays jersey.
How: A friendly and long-running pop culture mix-up reignited online chatter.
Shane Bieber, born in Laguna Hills, California, has long been the subject of playful comparisons to Justin Bieber, the Ontario-born global pop superstar behind hits like “Sorry” and “Peaches.” Their name coincidence dates back to 2018, when Shane famously wore a “Not Justin” jersey during Major League Baseball’s Player’s Weekend — a move that quickly went viral.
Justin responded in kind, sharing an image of himself in a custom jersey labeled “Not Shane Bieber,” cementing the joke as one of baseball’s most memorable crossover memes.
Player and Fan Reactions
In interviews over the years, Shane Bieber has leaned into the joke rather than avoiding it.
“A lot of people like to make the joke and mistake me for him,” Shane said in 2018. “So I figured I’d make it obvious and play along.”
During Game 3 of this year’s World Series, Justin Bieber was seen cheering from the stands wearing a Blue Jays No. 57 jersey. The moment went viral after Kara Bieber, Shane’s wife, posted a short clip on social media showing the pop star applauding during the seventh inning stretch.
Sports analysts noted that such celebrity appearances often draw wider fan interest beyond baseball’s core audience — something Major League Baseball has embraced in recent years.
Impact and Pop Culture Crossover
The “Bieber connection” has become an enduring lighthearted tradition. As Shane Bieber takes on a pivotal role for the Blue Jays in Game 4, the narrative adds an unexpected twist of entertainment value to an already high-stakes series.
Toronto currently trails 2–1 against the Dodgers, and Shane’s start could be crucial in leveling the matchup. Meanwhile, fan chatter about the “two Biebers” has helped make this one of the most talked-about World Series moments of the decade.
What’s Next
Game 4 kicks off tonight at 8:00 PM ET at Dodger Stadium, where Shane Bieber is expected to pitch for Toronto. Whether or not Justin Bieber returns for another courtside (or rather, field-side) cameo remains to be seen — but the “Bieber vs. Bieber” buzz shows no signs of slowing down.
