when had justin bieber had his firs キッス

In an interview, he 発言しました he made a bet saying who ever kissed a girl first gets 10 dollars. He was slow dancing w/ a girl at his school dance(b4 he was famous) and he just kissed her.

Well as あなた know his first 愛 was when he was 13 but he actually got his first キッス in a slow dance as momoandjustin stated
