ISLAMABAD-Justin Bieber threw it back to the ‘90s with an impromptu, shirtless cover of K-Ci & JoJo’s “All My Life.”

“Not sure I nailed the words but u get the vibe,” Bieber captioned the Instagram clip, which was filmed by Alfredo Flores. In the video, he’s seen performing the chorus of the single off of 1997’s Love Always: “All my life I’ve prayed for someone like you/ And I thank God that I, that I finally found you/ All my life I’ve prayed for someone like you/ And I hope that you feel the same way too,” he croons.
