London, Oct 14 : Singer Justin Bieber went back to school when he was here for his ongoing 'Purpose World Tour'.
Ahead of his show at the O2 arena, Bieber spent his downtime joining some boys for a soccer game earlier this week, reports aceshowbiz.com.
Bieber was driving past a school in Highgate, north London, when he saw the students playing.
"Justin and his manager came over to speak with us -- I recognised him straight away. They had been driving past and seen our lesson going on," teacher Mario Noto said.
"They explained Justin was in town for his shows at the O2, that he enjoys his football, and would love to join in. We thought this would be a great experience for the pupils."
"He (Bieber) was very down to earth and could have been another pupil, just enjoying himself, and spent about half an hour with us. He asked me to go in goal for a few penalties -- and turned out to be pretty good," Noto added.
During his surprise visit, Bieber also took time to take photographs with the students. Donning a bright green vest and holding a soccer ball, he smiled at the camera while surrounded by a group of boys who mostly sported red uniforms.
