When you take 17 celebrities and ask them all to walk in a single fashion show, mayhem ensues. Such was the case backstage at the Red Dress Collection 2010 fashion show tonight.

Celebrities like Heidi Klum, Kim Kardashian, and Bethenny Frankel all wore red dresses to support women's heart health awareness. And since it takes a lot of time (and a team of people's effort) to get 17 celebrities ready, needless to say the show did not start on time.

First to hit the red carpet on her way to the show was Heidi Klum in a John Galliano dress. Since the topic of the evening was health, I decided to ask perennially-fit Klum how she deals with unhealthy cravings.

"I have a lot of unhealthy things that I crave, definitely," Klum admitted. "But, you know, that's not my day to day living. I couldn't run around, have four children and work and have healthy hair and skin and just be able to get up in the morning with a smile on my face if I wouldn't eat right." Figured as much.

Klum preaches the moderation principle: "You can have some guilty pleasures -- chocolate, I love some chips sometimes, I like like a Big Mac sometimes -- I love Big Macs and barbecue sauce! But you know, my day to day is very healthy." As she was shuttled away to prepare to walk the runway, we asked if Heidi had any beauty secrets to share. "Schwartzkopf!" she called out. Looks like the German-born model is staying true to her hair's roots.

After Klum departed, I caught Kimora Lee Simmons on her way to the runway. I asked the curvy mom if she had any flattering fashion tips for normal-sized women.

"I have learned a lot," Simmons said. "Believe it or not, form-fitting things and things that grab you in and give you great support make you look streamlined. It's not always about wearing frumpy things!" she says. "I have three kids, I have not been a size two since I was on the runway at 13," the former model added. I was about to ask one last question when we were nearly blinded by the sight of Simmons' unbelievably gorgeous diamond ring. As I'm gunning for one of those babies myself, I asked "Let's see that ring! Is it custom made?"

"Yes, this is my wedding ring from my honey," Simmons said.

Next up, I saw Kim Kardashian following Klum and Simmons as they all headed to the runway. "Is there anything healthy you eat to help stick to your diet?" I asked the newly slimmed-down star.

"I'll eat like, Pop Chips. Those are healthy and good and it makes me feel like I'm getting what I'm craving without all the fat."

And with that, it was time to start the show. As I made my way out of the dressing area backstage, I passed Jordin Sparks, who was just jumping into her dress and wasn't going to have time to give interviews before the show.

"I can't do this!" a time-weary Sparks confessed to her publicist, noting the line of media waiting around the corner. "Just walk by and wave," Sparks' publicist suggested, seeing that Sparks didn't want to disappoint the press. "Are they gonna be mad, though?" sweet Sparks asked. "My hair's already getting frizzy!" Talk about a good excuse! I smiled at Sparks to let her know, hey, a girl's gotta do what a girl's gotta do. If your hair is getting frizzy and your show's about to start, we won't hold it against you! As I turned the corner to find my seat for the show, I heard Sparks oblige a journalist's request for a quick song.

What a trooper! (And what a gorgeous voice!)
