This is Justin Bieber at his most vulnerable state, when the singer began epically sobbing on-stage.

The Biebs delivered a spot-on performance of his summer hit, “Where Are U Now,” and his single, “What Do You Mean?” — even flying up into the air at one point — but then he broke down in tears at the end of the set.

With no explanation at all, Bieber sobbed into his hands while a stunned crowd looked on.

Naturally, all eyes were searching for Bieber’s ex-girlfriend Selena Gomez, who was attending the show alongside her pal Taylor Swift and the “Bad Blood” squad.

So where was Gomez while all this was going down?

Gomez, along with Swift and the “Bad Blood” girls had exited the venue just before Bieber’s set.

So the world will never know how she might have reacted to those tears.

Hailey, 27, took to her Instagram Stories and shared the couple’s night out in Toronto.

On Thursday night, Justin, 29, performed at the History Toronto venue in Ontario, Canada.

Wayne Gretzky’s daughter-in-law, Sara Gretzky, also attended the concert, according to Sportskeeda.

In the first Instagram Story, the Rhode founder pointed at the projector screen as the Canadian pop singer crooned his lyrics.

Justin wore a blue and yellow NHL jersey and his black cap on backward.

“Correct,” she captioned the post.

In the following Story, Hailey continued filming as her singer switched to an upbeat track.

“Here’s your Justin Biber Eras performance.”

In the last Story, the supermodel uploaded a snapshot of herself as she stood in front of the white projector screen.

While wearing a furry coat and covering her eyes with black sunglasses, she flashed a finger at the camera.

Hailey pulled her brunette hair tightly back, except for two curly strands in front of her face.

Justin’s concert came ahead of his upcoming appearance as celebrity team captain for the 2024 NHL All-Star Game in Toronto, according to Billboard.

The All-Star Game will be held on Saturday, February 3, at the Scotiabank Arena.
