Got some burning questions for Jessica Simpson?

Us Weekly's Style Icon of the Year hits our Hot Hollywood bash Tuesday night at L.A. hotspot Eden -- and in honor of her big night, the 30-year-old designer, mogul, singer and bride-to-be is answering fan queries via Twitter!

"This year, I've taken time for myself to enjoy being engaged and in love and being a businesswoman instead of an entertainer," Simpson told Us in last week's issue. "It's really helped the collection!"

Tweet your Jessica Simpson questions to Us Weekly's official Twitter account -- and use the "#HotHollywood" hashtag.

And check out Us Weekly on Wednesday morning for full red carpet coverage of our star-studded Hot Hollywood blowout!
