Chris Brown Stars in Naomi Campbell's Fashion for Relief Haiti Show

Kelly Osbourne, Malin Ackerman, Estelle also take the runway while Victoria Beckham hides in the wings; Rachel Zoe styled and Alexander McQueen honored

Fantastic Haiti relief efforts haven't halted, nor has the need for them.

Naomi Campbell did her part tonight, throwing a Fashion for Relief runway show during Mercedes-Benz Fashion Week at Bryant Park. And not only did she get some of the biggest names in the modeling world—Karen Elson, Helena Christensen, Selita Ebanks and Agyness Deyn—to participate, but she called some of her celebrity pals as well.

Kelly Osbourne, Malin Ackerman, Alan Cumming and Estelle did their little tricks on the catwalk, but it was Chris Brown looking dapper in a tux that had the audience going wild.

Heck, she even got Victoria Beckham to don a "Help Heal Haiti" T-shirt for the gathering, even though she was just a spectator.

"[Events like this] are definitely important, not necessarily for me," Brown tells E! News backstage before the show. "I think it's important for Haiti because you get a chance to see artists and entertainers and fashion icons come together to do something nice for a good cause and it's not so snobby. It's very humbling and being able to come and help, it's nice to see."

Also heard backstage beforehand: Kelly showing Naomi the shoes she'd be wearing and expressing her trepidation about them.

When asked about those nerves, all she can tell us is, "You don't even know," and she admits this is more terrifying than taping an episode of Dancing With the Stars.

"I'm not a model," she insists. "I'm five-foot-two and dumpy! And I'm going to be walking down the runway with Agyness Deyn and Naomi Campbell—it's crazy!"

But fear wasn't about to keep her from contributing to a great cause. At least it wasn't her first time. Kelly participated in Naomi's Fashion for Relief show raising money to help victims of the tsunami in 2004.

"When you really think about it, I get a personal invitation from Naomi Campbell for the second time in a row doing a charity event where they give me an amazing dress to wear and all I have to do is walk down a runway so someone can see it so they can auction it off. That's nothing for me to do. It's fun for me to do. And it sends such a great message that the fashion industry is supporting it," she says.

Rachel Zoe pulled together the 92 looks that filled the show, including the moving finale tribute to Alexander McQueen that saw the most famous models gathering at the end of the runway and holding back tears.

The dresses from the show are being auctioned off on Net-A-Porter.com beginning on March 15 and the funds, as well what's raised from the cost of the tickets, will benefit CARE's work in Haiti.
