Bieber fans wait outside Jingle Ball concert for 13 hours

BOSTON (WHDH) -- Some of today's biggest musical acts were back in the Bay State Thursday and jingled all the way to TD Garden for Kiss 108’s Jingle Ball.

Among the performers: Justin Bieber, The Wanted and Berklee College of Music grad, Karmin. Lindsay Lohan was also at the concert backstage trying to fly under the radar.

There was no question about who some screaming girls were at the Garden to see.

“I just love Justin Bieber. I would do anything to meet him.”

Some fans showed off homemade T-shirts.

“Jingle Ball 2012 Boston and on the back it says, all I want for Christmas is Justin Bieber.”

Others showed off posters and cut out hearts.

“They're hearts that say Beliebers…it’s just Justin Bieber’s family. They all say different things. This says Jingle Ball. The red one says Kiss 108.”

Dedicated “Beliebers,” have been waiting outside TD Garden since 6 a.m. hoping to get a glimpse of Bieber.

“We love the Biebs. We skipped school and everything. We’re dedicated.”

The concert began at 7 p.m. Bieber took the stage shortly after 10 p.m.
