Life comes at you fast sometimes, and sometimes you become a father when you least expect it. Some boy band stars found themselves become parents at a time when they least expected it. Some of these guys found out the news at the beginning of their careers, while others became dads at the height of their fame and others when they were just teenagers!
While it can be shocking to become someone's dad and it would surely take some getting used to, these famous dads are excelling at their new roles. There is one guy in particular that must currently be a nervous wreck since it is suspected that he has a little one on the way. ;)
