Justin Bieber is rollin' with a different crew.
A source tells E! News exclusively that the Biebs recently hired a new security team "about a week and a half ago."
"I don't know why, but I know some former security guys have felt like they were babysitting him," says the source.
The insider added, "They [the new team] are working around the clock. They are working the hardest they have ever worked. He is all over the place."
Keeping up with the Biebs is no easy task.
