Melbourne, Jul 9 : American actress Jessica Biel has agreed to bare all for the first time on screen, but she is adamant that she will never go commando.

Biel, 27, who is currently dating singer Justin Timberlake, has revealed that she would never leave the house without her knickers on.

"I don't really get that, it's not my thing - I'm a knicker person," the Daily Telegraph quoted her as telling Manhattan Movie magazine.

"I actually know a handful of people who aren't knicker people, but I don't get it!" she added. (ANI)
