Ah, it all makes sense now ... especially after last night's cotton candy pink 1990s prom dress!

Jessica Biel is busy promoting Total Recall (today she stopped by The Daily Show With Jon Stewart in NYC), and the 30-year-old actress revealed that she counts on fiance Justin Timberlake for tips when it comes to her wardrobe.

Jess told The Sun, "We both really love fashion. There are definitely moments where I'll come out in an outfit and he'll give me that look! He'll take me back into the closet and I'll change my shoes and I'm like, 'Yeah, this is way better.'" However, she doesn't always agree with his suggestions. She added, "Sometimes I won't change!" Hmm, so maybe she should be listening to him? We'd love to know when he's the one calling the shots on her outfits!
