YOU ASKED: What was your first fragrance?
GWEN SAID: "Love's Baby Soft. Probably because it was the one that I saw over and over again in commercials. I've always been into beauty products. As a kid one of my favorite stores was Sav-On Drugs. I just loved the smell of L'Oreal lipstick."

YOU ASKED: Is there a new look you're dying to try?
MANDY SAID: "People have this perception of me-and obviously I do too-as being natural and flowy and girlie, so I'd love to wear something tougher and more masculine and structured. Strong! I've never done something like that before, and I think it would be fun. I have some events coming up, and I've been toying with the idea of wearing a really cool, funky tailored suit. Even wearing a vest with a white T-shirt and jeans is a more accessible riff on the whole masculine thing. I used to wear suits when I was 17 or 18, so it's all coming full circle for me."

YOU ASKED: What's George Clooney really like?
CATHERINE SAID: "George is the biggest goofball in the history of goofballs, and I love him. Here's a story: During the filming of Ocean's Twelve, he told me, 'Come stay with me in Italy.' So I called him a few months later and said, 'It'll be me, Michael, two nannies and two kids.' He went, 'What?! I always invite people to my house, but no one has ever called and said, I'll be there next Thursday.' But I do. Invite me to your house, I'm turning up."

What do you look for in a man?
"Confidence is key, and I like someone who's evolving. I think that's really important. Someone who's open to change and knows that you can only be happy in life if you're growing. I'm learning that, as many answers as you could ever have, there's always another experience to open your eyes up to something in the world and in yourself."
