NEW YORK -- Ashlee Simpson is amped about her upcoming tour -- but doesn't want to talk about her embarrassing ''Saturday Night Live'' or Orange Bowl appearances.

Simpson turned up Monday at the Cosmopolitan Fun Fearless Male Awards in New York.

''It's really stripped down,'' she said about her first solo tour, which comes to the Rosemont Theatre on March 6. ''There's no pyro[technics] or anything like that. The stage has a mud kind of feel, you know, black and white. The thing about my tour is it's going to be me and my bad getting out there and having fun.''

Of course. But will there be costume changes?

''Little ones here and there,'' said Simpson. ''I'll be taking off jackets and that kind of stuff.''

The 20-year-old pop star was unsure about why Cosmo, in its February issue, picked her as the Fun Fearless Female of the Year .

''Oh, wow. I don't know,'' said Jessica Simpson's little sis. ''I love to have a great time. I'm not really scared of many things at all. I've been that way since I was a little girl.''
