Think about it; someone is less likely to post a video of him snoozing on YouTube if said someone is already on the payroll.
The 19-year-old singer is reportedly growing increasingly "paranoid" about crazed fans breaking into his hotel room (it's the ones you invite in you need to worry about, sunshine) so has employed a 24-hour "army of giants." He even has two in reserve to cover when his regular minders need breaks.
A source said: 'Justin can't be alone at night right now. He is paranoid about fans breaking into his room, and he hears noises all the time. It freaks him out. As well as the ever-present guard in his room and the one outside, he also has two on standby to take over when his men need breaks. All of the burly guys are around 6ft 5in tall and weigh around 250lb. He wants an army of giants protecting him."
Even when his world tour concludes in Australia next week, he has no plans to ease off his tough security arrangements. The source - who is bound to be helping Justin's paranoia no end - added to the Daily Star: "Justin is now used to having a guard watch him sleep and he wants the arrangement to continue after the tour finishes."
Despite being protected by burly security guards, this hasn't been enough for the teenage star - he also cornered his mam Pattie Mallette to accompany him on the road for extra reassurance.
The source said: "He also begged his mother Pattie to accompany him on most of the concert dates. She was asked to combine her book signing tour with his gigs because he gets so anxious."
Pattie recently who recently released a book, Nowhere but Up: The Story of Justin Bieber's Mom. Again, helping with the paranoia no end. Way to be as nurturing as Lynne Spears.
