Jessica Biel gets festive for the December issue of British Marie Claire magazine.

Inside the mag, the actress opens up about the trappings of fame (i.e. the battle with age, plastic surgery, etc.) and even dishes on whether she’s thinking about marriage and kids with beau Justin Timberlake.

Some highlights:

Jessica on Posing for photographers: “It’s taken a few years to feel comfortable doing that sort of stuff. Even now I still feel sort of ridiculous.”

Jessica on music: “I like all that fun music, lots of old-school stuff and yes, some Whitesnake. Absolutely.”

Jessica on her recent interest in popular music: “I was sick and tired of not knowing who people were talking about.”

Jessica on becoming a movie star: “I never thought to myself, ‘I’m going to do this musical, then I’m going to be a movie star.’ I never made that jump. For a very long time I wasn’t thought of as anyone with any credibility in the film world. Everyone is tramping through the swamp everyday in this business.”

Jessica on working in TV: “I was really up tight, when you work on television for a long time you’re in a really organised situation; in film, it’s so much more improvisational and relaxed.”

Jessica on being in the film The Illusionist: “I was so thrilled to get that part, it was such a joy for me, oh it was great.”

Jessica on how she feels about aging: “I don’t know - I better start figuring it out. I feel my knees changing – like, why do I have this pain when I’m running on the treadmill? What’s going on with my lower back when I wake up in the morning? I just feel changes. I’m definitely fearful in a very vain manner about aging. I think its freaky weird to look at a picture of your grandmother when she was a young woman then look at her now.”

Jessica on plastic surgery: “I’m really afraid of blades on my face. That freaks me out beyond belief. I would way rather have wrinkles than some slice up going on.”

Jessica on her high profile status: “It’s hard. The hardest part of this whole wonderful, bizarre lifestyle and profession. You have to be Zen about it, because it can make you crazy.”

Jessica on marriage and having kids: “I kind of go back and fourth about marriage and kids. I feel like if it’s an organic way for me and the right time in my life then yeh. If it’s right, it’ll be right – but at this moment, that seems totally foreign.”
