Jonas Brother mania is climbing to a fever pitch as hundreds of music fans continue to camp in downtown Toronto for the third day in hopes to snag wristbands to this year's MuchMusic Video Awards (MMVAs).

The fans and some parents have been parked in line starting at MuchMusic headquarters at the corner of Queen and John Streets through both rain and sweltering sunshine. They're hoping to get their hands on wristbands so they can get a glimpse at the Jonas Brothers, who will be co-hosting the awards on June 21.

"I missed my math exam to be here," said Emily Wild, who along with her friends Rachelle Monette and Charlie-Ann Aucoin, all 15, have been at the front of the line since 4 p.m. Wednesday. Wristbands will be handed out at 8 a.m. on Saturday.

"If I get a low mark in math versus the MMVAs once in a lifetime....I can redo math," she said, explaining that she also has her mother's blessing to miss the test.

"We have been hardcore Jonas fans since 2006. They're a Christian Rock band. They're like, really talented and they're hot," Wild explained.

"We went shopping especially for this trip," said Monette, pointing out the green and grey tent, inflatable sofa, bottles of water and other supplies the girls brought to help them survive their four day camp out. They used the same strategy when they were among the throng of fans who lined up for the brothers' appearance on Live@Much last July.

Monette's parents take turns driving from Hamilton to deliver food and money and check up on the girls, who try to fight the boredom as best as they can by chatting and reading teen magazines.

At about 5 p.m., the lineup was growing so long that fans were asked to take down their tents to make more room for others. The lineup circled around the John Street and Richmond Street West building that is home to MuchMusic and CP24 and stretched all the way to University Avenue.

Alicia DelFuoco, 17, nursed a possible torn ligament in her right leg and stood on crutches for her love of the Jonas Brothers and Lady Gaga, who will be performing at the awards. She sat through Tuesday's downpour.

"With the rain and the pressure, it was not fun last night," she said. "I sit and ice it all day, but it's going to be worth it."

"I've never seen so many girls go crazy over three guys," said dad Robert Rossi, who drove from Ancaster to spend time with his daughter Simona who wanted to get in line.

He says he is happy to camp out.

"It's a good way to bond and there's five girls from Waterdown (next to us). I'm their father today."

"Youth culture today is all about music, iPods and cell phones. It's a great way to keep kids engaged. More parents should get into their kids' lives. This is the way to go," said the dad, who plans on also claiming a wrist band and going to the show.

Rossi even kept his daughter's place in line while she went to check out a taping of Much on Demand.

"I'm doing this for my daughter. Hopefully when one day I'm in another place she'll remember this," he said.

A number of fans sheltered themselves from the sun under a bright blue tarp they had taped to the wall and the barrier. Others brought patio umbrellas. A number of people in line sported sunburns. 

The hundreds of teenage girls in line even turned into a business opportunity for members of independent alt-rock band Andrew F. They showed up with a large green cooler filled with ice and cold pop in hopes that people in line would request the video for their song "The End," on MuchMusic. The video first aired last month.

"We're trying to promote the video and the fan base," said Matt Boutin, 17, who plays bass and backup vocals for the band.

The MuchMusic Video Awards will air live on MuchMusic on June 21 at 9 p.m.

There is a long line for wristbands every year, but organizers say the hype over the Jonas Brothers' appearance is bringing more people down to get their hands on a wristband. 

The Black Eyed Peas, Girlicious, Kelly Clarkson, Nickelback, and Billy Talent are just some of the musical performers.

Celebrities that will present the awards and walk the red carpet include reality star Kim Kardashian, Taylor Lautner from the Twilight movies, Anna Lynne McCord from 90210, and Audrina Patridge and Brody Jenner from MTV's The Hills.
