We've finally uncovered Victoria's big secret! The Angels' tushes are not as flawless as they appear on the runway.

"It's all about creating the illusion of a perfect body," Victoria's Secret model Selita Ebanks told the New York Daily News, referring to the annual Victoria's Secret fashion show. "People don't realize there are about 20 layers of makeup on my butt alone."

The Angels prep in hair and makeup for 3-5 hours before strutting down the runway, with an average of five people, including hairstylists, makeup artists and manicurists, working on each of the 38 models, reports the Daily News.
