Christina Aguilera, Bruce Springsteen and Jon Bon Jovi are performing for Friday's benefit concert.

NBCUniversal's benefit telethon "Hurricane Sandy: Coming Together" kicked off on Friday night with "Voice" coach Christina Aguilera. 

"We've come together tonight to tell every single person who's suffering that we are here for you. We will do whatever we can to help. We will not leave anyone behind because every single one of you matters," the star said before beginning her performance of her hit "Beautiful."

"We haven't seen a storm like this in 100 years," said Matt Lauer, who hosted the event.

The show also featured Jon Bon Jovi surveying the devastation in New Jersey, the performer's home state. After the touching clip, which also showed the rocker talking to impacted residents, he performed an unplugged version of "Living on a Prayer." Images of the destruction caused by Superstorm Sandy were also interspersed throughout the show, along with victims pleading for aid, reminding viewers just how immense the damage was.

"New Jersey was hit really hard. Some beaches were destroyed. Boardwalks were torn apart. But they will be rebuilt. This song is dedicated to all the good times ahead," late-night host Jimmy Fallon said before joining Steven Tyler, Billy Joel and Bruce Springsteen for a cover of "Under the Boardwalk."

"That ain't bad! ... Jimmy Fallon is a bold man to take the lead vocals," Jon Stewart joked after their performance before getting serious again. "You never think that it's going to be your home or where you grew up, now that it is, I find it more difficult (to ask for your help). ... We're asking for your help. Text, call, whatever you can do for the Red Cross."

Other stars scheduled to perform include Kevin Bacon, Mary J. Blige and many others.

Just hours before the concert kicked off, NBCUniversal also announced that Steven Tyler and Joe Perry of Aerosmith, as well as comedian Whoopi Goldberg, would join the one-hour live show. 

Money collected during the concert will be donated to the American Red Cross relief efforts. The Red Cross is providing shelter, food, emotional support and other assistance to those impacted by disasters such as Hurricane Sandy. As of Friday, the death toll in the U.S. from the storm neared 100 victims.
