The Baby hitmaker was on hand for the Opening Ceremony at the Los Angeles Coliseum in California, and met with the representatives from Canada as they prepared to take the field for the first time.

He shared a video on of himself chanting, "Let's go Canada!" with the athletes, as he attempted to pump them up for the next nine days of competition.

U.S. TV personality Maria Menounos also shared a backstage photo on, featuring her alongside Bieber, his Australian singer pal Cody Simpson, and Maria Shriver, whose mother Eunice Kennedy Shriver founded the Special Olympics.

Menounos added the caption, "Justin gave me a sneak peak of his new single-so cool! he even sang along which was even more cool!"
