As longtime rivals on rival teams, Capitals star Alex Ovechkin and Penguins star Sidney Crosby should hate each other. So what happened to make Ovi say this?

Asked Ovechkin if he's buddies with Crosby now. He cracked: "Yeah, best friends. How I always said." #NHLAllStar — Tarik El-Bashir (@Tarik_ElBashir) January 30, 2017

The two were linemates representing the Metropolitan Division in tonight's NHL All-Star Game. Crosby even set up Ovechkin for a goal.

Crosby → Ovechkin → GOAL! 🚨

The odd-couple dynamic didn't go unnoticed by their teammates in the All-Star Game. P.K. Subban couldn't believe the two were hanging out.

Ovechkin responds by accusing Subban of being jealous of their friendship.

What world is this?
