The Backstreet Boys have a secret to looking good -- Donatella Versace.

The American boy band hunks are dressed almost exclusively by the hip label since stylish Donatella took them under her wing.

Howie Dorough explains, "Our relationship with Versace started by accident. We went to Monte Carlo to play at the World Music Awards and the airline lost all of our luggage. We didn't have anything to wear. So we called Versace and asked if they could help out.

"Straightaway Donatella was on the phone. She told us to get down to her store and pick up whatever outfits we wanted. She's been great to us ever since."

Kevin Richardson adds, "Two years ago she invited all five of us to a show in Milan. On the first day we just watched. On the second day Donatella asked me to model in the Versace show.

"That night, I was sat at dinner between Donatella and Naomi Campbell. It was my birthday and Kate Moss walked in with a cake.

"I couldn't believe it was happening." -- WENN
