NEW YORK CITY -- Bieber fever is spreading outside NBC's studio in Manhattan.
Fans of Justin Bieber have been camping out along W. 48th Street for days to make sure they get a chance to see the teen idol perform at a free concert for the "Today" show on Friday morning.
The line started forming around 6 a.m. Tuesday and it's been growing by the hour.
The line stretches for blocks.
Fans have endured heavy rain and some have been sleeping on pool floats, but they say it will be worth it to see their idol in person.
