OM: When I knew I was going to guest edit InStyle.com, my first thought was that I had to talk with you because you're one of the most beautiful, smart, sweetest, real people in the world. I guess we should tell people how we met and became friends! I was walking by your table at the Golden Globes and I saw you and just had to tell you how brilliant and wonderful you are and how much I loved you and then I ended up taking someone's seat at your table.

JM: That's right! And I asked you about your freckles and we started talking and found out that we both had moms from other countries and I sent you my book My Mom is a Foreigner.

OM: I love that book and was so excited to get such a sweet gift from you. I read the book to my niece who is a quarter Chinese. I think every kid should read it, even if their parents parents aren't foreigners. It teaches understanding.

JM: It's nice, especially for kids who have parents from another culture. But I liked you right away. Because you're talented and funny and you were so pretty when we met.

OM: You're so nice! So we gotta talk style. You have such amazing style and you always look so at ease on the red carpet. Are you?

JM: Oh no, totally not. I think it's my least favorite part. I mean, I love clothes—I love shopping for clothes, I love wearing clothes, I love talking about clothes, but oddly putting on the dress and walking around in front of people, that's the place where I'm most uncomfortable. I always admire people who can really own it, who can work the dress and take the picture… I always feel a little silly doing it.

OM: So what's your advice to look comfortable on the red carpet?

JM: You know what I think—go with someone you like. Every time I take a picture with someone I genuinely like on the red carpet I think I look terrific. I'm laughing, having a good time. Like I really like the picture Bart [Freundlich, Moore's husband] took of us at the polo event! We're having so much fun! That's the key. I went with Tom Ford to a bunch of events one year and he's so wonderful and handsome and so much fun to be with he made me look like 100 percent better in every single picture.

OM: What do you do when photographers start screaming, "Blow us a kiss!" or, "Over your shoulder?"

JM: No. No I won't do it. One of the thing's that happens to me, 'cause I laugh really hard, and sometimes I'll laugh and retract my head and end up with a triple chin. There's a picture of me and Meryl Streep at the Oscars that ran years ago and I was like, "Oh no!" There's my triple chin!

OM: Whenever I smile, my eyes can open up really wide and I look like a deer in headlights so years ago I decided I would rectify that by closing my eyelids halfway on the red carpet. Oh yes. What ended up happening is I just look high. But I've been doing it for so long I don't know how to stop! If I don't remind myself before I hit the red carpet, I will for sure look high [laughs]. So, you're really good about staying out of the sun.

JM: I am. I have to be. I always tell my kids the number on the SPF is how long you can be out in the sun. I can only be in the sun for 15 minutes before burning. I have sunscreen on my face everyday. If I'm walking on the sunny side of the street, I'll walk to the shady side. I'm too uncomfortable in the sun. But the great thing about it is because I always felt that way--it really has helped my skin in the long run.

OM: Do you like wearing makeup?

JM: I do. I certainly like it for my job, I think it's great. I tend to not wear a whole lot of it when I'm not working. I have a contract with L'Oréal so I wear a lot of their stuff. There's a L'Oréal mascara I've worn for years and years, and the Yves Saint Laurent Touche Éclat (concealer pen)—I love that. L'Oréal has a new beauty cream that I really like that smooths out your skin and is not so heavy. Also, I always use an eyelash curler. And L'Oreal has this new thing, Balm Pop, and I'll use that on my lips and my cheeks. I'm putting on some right now--I wish you could see me.

OM: Aww, where are you going?

JM: I'm going to go to my acupuncturist. They're really great and it's nice to start off the week with it.

OM: People don't realize that acupuncture isn't hippie dippie, it really truly works.

JM: Yeah, it does. I don't really understand it but it works.

OM: Before we finish up, what's your best beauty advice?

JM: Skin quality. It really is the skin quality. And also, to use less. Less really is more. The idea behind makeup is to enhance whatever color or contours you have in your face. I'm a big believer in that. And don't use to much powder; powder is really aging. I've made that mistake myself.

OM: There's a big thing I've learned working with makeup artists. Powder just sits on top of your skin and accentuates your wrinkles--it makes you look older, no matter what age you are.

JM: Old. Yes. Put the powder down. Then you can do all the other fun stuff.
