Justin Bieber reps Toronto Blue Jays at World Series in L.A.

There were at least three Biebers in attendance for Game 3 of the World Series between the Toronto Blue Jays and Los Angeles Dodgers.

In Toronto's dugout, Game 4 starter Shane Bieber watched the two teams face off ahead of his scheduled appearance on Tuesday night.

But in the crowd at Dodger Stadium in Los Angeles, Canadian singer Justin Bieber and his wife Hailey were cheering on the Blue Jays.

Bieber also posted a photo from his seats, located in the first row down the first base line.

Justin was wearing a No. 57 Blue Jays jersey with "Bieber" on the back. That's actually Shane Bieber's jersey. 

Is Justin Bieber a big Blue Jays fan?

A native of Stratford, Ontario, Bieber has been a longtime supporter of many of Toronto's teams. His closest association is with the Toronto Maple Leafs, having a strong friendship with team captain Auston Matthews.

Bieber has been a staple at many Leafs regular season and playoff games over the years, most recently appearing at a second-round Game 7 loss to the Florida Panthers this past spring.

But given that he spends much of his time out in California, it's probably not exactly the longest commute for him to check out the Jays in the World Series.

Toronto infielder Bo Bichette likely would get fired up a little if he happened to spot the star in attendance, given that he uses Bieber's hit song "Peaches" as his walkup music.
