In Hollywood, most actresses are ready to let inquiring minds know exactly what designer they are wearing on the red carpet.

But when Brittany Snow was asked the question by a People magazine reporter standing next to me on the red carpet of the 15th annual Diversity Awards over the weekend, I just loved her honest reply: "I don't know!"

Then she explained.

"It's been a long night. I had something else to wear, it got ruined. I, at the very last minute, pulled this out of my closet. That's why I'm not exactly sure."

The blond-haired, blue-eyed beauty also seemed perplexed about why she was receiving an award as 2007's rising star from the Multicultural Motion Picture Association when the character she played in the musical smash "Hairspray" was a racist.

"My character didn't like anybody except for herself so that's not very diverse," she said. "It's nice that they recognize that I'm not like my character and that they appreciate the movie and what it stood for."

The movie, one of the highest-grossing musicals in Hollywood history, was released on DVD on Tuesday. It's the biggest hit of Snow's career, which also includes the films "John Tucker Must Die" and "The Pacifier" and a recurring role on television's "Nip/Tuck."

Brittany, who gained fame on the series "American Dreams," hopes people are not only entertained by "Hairspray" but take home the message of tolerance and acceptance of people different from you.

"I'm just really grateful that people have loved it and taken it to their hearts," she said. "The movie has a great message that it shows in a very light-hearted way. It's not hitting you over the head. There is a great message about acceptance and believing in yourself and accepting people for their differences, no matter what it is. All at the same time we are singing and dancing. What better way to get a message across?"
