While some fans wondered if the Biebs would join the "Caught Up" singer on the Allegiant Stadium stage on Feb. 11, he ended up ultimately fulfilling a different purpose: being a supportive friend from the stands.
And social media users speculated that Usher, who first discovered then-13-year-old Justin alongside Scooter Braun in 2007, might be able to get his protege back at the mic again as they've remained friends over the years.
"Our relationship is more man-to-man now," Usher, 45, told The Hollywood Reporter in 2014. "I'm supportive of him. I try my hardest to give as much positive reinforcement as I can. I'll punch him in the f--king chest when I need to, and give him a hug and kiss when I need to. It's more than just mentoring. I love the kid."
